GPS Tracker Buying Guide NZ: How It Gets Power Decides Everything

Almost every GPS tracker sold does the same thing. What separates them is how they get power, and that single question decides which of the fifty-seven models here you should be looking at.

A tracker wired into a vehicle never needs charging and never needs thinking about. One on a magnet under a wheel arch goes anywhere in ten seconds and has to be retrieved and recharged on a cycle you have to remember. One worn by a person is charged like a phone. A Bluetooth tag has no GPS in it at all and costs nothing to run.

Get that decision right first and the rest is detail. Get it wrong and you have a flat tracker on a vehicle you can no longer find.

Before you buy: tracking a person without their knowledge is a criminal offence in New Zealand. The Crimes Legislation (Stalking and Harassment) Amendment came into force on 26 May 2026 and carries up to five years. This applies to a partner, an ex-partner and an adult family member. Read the section below before you order anything on this page.



GPS Tracker or Bluetooth Tag

Two completely different products sold under similar words, and buying the wrong one is the most expensive mistake on this page.

A GPS tracker knows where it is. It reads its position from satellites and reports it over the mobile network. It works anywhere with coverage, updates on a schedule you set, and needs a SIM and a monthly data plan.

A Bluetooth tag has no idea where it is. It sits there broadcasting, and waits for somebody else's phone running Apple Find My or Google Find My Device to walk past, notice it, and report the location. No SIM, no plan, no charging beyond a coin cell.

The rule that decides it

A tag works in proportion to how many phones pass through the area. In a suburb, a school route, a car park, a city street, the Find My network is dense and a tag performs remarkably well for nothing per month. On a rural road, a farm, a bush block or an industrial estate at night, there are no phones to borrow and a tag will tell you nothing.

So the question is not what you are tracking. It is where the thing goes when it goes missing.


How It Gets Power, Which Decides Everything Else

Five answers, and each one rules out most of the range.

Hardwired into the vehicle

Wired to the loom, usually behind the dash. Never needs charging, cannot be knocked off, and the good ones carry a backup battery so they keep reporting if the power is cut, which is exactly what a thief does first. The cost is installation: this is an auto-electrician job unless you are comfortable with vehicle wiring.

Buy hardwired when the tracker lives in one vehicle permanently and you never want to think about it again.

OBD2, plugged into the diagnostic port

Every car built since the mid-2000s has an OBD2 port under the dash. The tracker plugs in, takes power from it, and works in about ten seconds with no tools. It also moves between vehicles just as fast.

Buy OBD2 when you want vehicle power without an install, or the tracker needs to move between cars. The trade is that it is visible to anyone who looks in the footwell.

Battery and magnet

The largest group. A sealed unit with a strong magnet that attaches to anything ferrous in seconds, with no install and no trace. Battery capacity runs from 5000mAh to 20000mAh and decides how long between retrievals.

Buy magnetic when the tracker has to go on something quickly, discreetly, or on something you do not own the wiring of, such as a trailer, a machine or a container.

Worn or carried

Personal trackers and watches, charged like a phone every few days. Built around a person rather than a vehicle, which is why they carry SOS buttons and two-way calling rather than ignition alerts.

A coin cell, or nothing at all

The Bluetooth tags. A replaceable cell that lasts about a year and no charging.


The Battery Numbers, and Why They Disagree So Wildly

You will see a 20000mAh tracker quoted at 420 days and a 6000mAh one quoted at 72 hours. Both are true. They are measuring different things and this is the single most misread specification in the category.

Real-time mode against sleep mode

  • Real time means the tracker holds a live connection and reports every few seconds. This is what you want while something is being stolen, and it burns battery fast. VIM-4GPS23 quotes 72 hours in this mode.
  • Sleep or standby means the tracker wakes on a schedule, reports once, and goes back to sleep. VIM-GPS4G-22 quotes up to 420 days in deep sleep, and VIM-4GPS24 up to 220.

The number you should buy on is neither. It is how long the tracker lasts at the reporting interval you actually intend to use. A tracker reporting every ten minutes sits somewhere between the two quoted figures, usually far closer to the shorter one.

Set the interval before you deploy it

Almost every unit here lets you choose. One report a day for an asset that should not be moving. Ten minutes for a work vehicle. Every ten seconds when something is actually happening, which is a mode you switch into rather than live in.

A useful habit: set the interval, charge it fully, deploy it, then check the battery after a week and multiply. That tells you the real retrieval cycle for your settings, which no specification can.

Two ways around the problem entirely

VIM-4GPS-101 at $217 carries a built-in solar panel that tops the battery up, so on anything that sits outdoors the retrieval cycle disappears. And on a vehicle, hardwiring removes the question completely.

For a battery unit you cannot easily retrieve, a 20000mAh power bank attached alongside extends a deployment considerably without changing the tracker.

Quick Picks

Best for one vehicle, permanently: VIM-GPS101G, $289

Hardwired and dual frequency, which is the feature worth paying for. A single-frequency tracker loses position in tunnels, multi-storey car parks and between tall buildings, exactly where a stolen vehicle goes. Dual frequency holds it.

Do not buy this one if you are not having it installed. It is a wiring job.

Best without an install: VIM-OBD2B, $200

Plugs into the diagnostic port, takes vehicle power, works in seconds and moves between cars just as fast. Live listening built in.

Do not buy this one if it needs to stay hidden. Anyone who glances into the footwell will see it.

Longest battery in the range: VIM-GPS4G-22, $255

20000mAh on a magnet, quoted at up to 420 days in deep sleep. For a trailer, a container, a boat or a machine that should not be moving, this is the one you fit and forget.

Do not buy this one if you need continuous real-time reporting. That figure is a sleep-mode number.

Best where you cannot retrieve it: VIM-4GPS-101, $217

A magnetic tracker with a built-in solar panel. On anything that sits outdoors it keeps itself charged, which removes the one genuine weakness of battery trackers. Live listening included.

Do not buy this one if it will be hidden under a vehicle in the dark. It needs light to work.

Best for a child or an older person: VIM-4GPSP6, $211

Wearable, five to seven days per charge, with SOS calling rather than only an SOS alert. The difference matters: a button that sends a location is useful, a button that opens a voice call to you is the one a frightened person actually needs.

Do not buy this one if the person will not wear it. A watch is easier to get accepted.

Best pet tracker: VIM-PET7, $278

Fifteen days of battery with live monitoring, which is roughly five times what most collar trackers manage and the difference between a device you charge fortnightly and one you charge every third day and eventually stop bothering with. Confirmed working in New Zealand.

Do not buy this one if the animal is a cat in a dense suburb. A Find My tag costs $77 for two and nothing per month.

Cheapest way in: VIM-TAG, $39

$39, no SIM, no plan, replaceable coin cell, works with Apple Find My and Google Find My Device. For keys, a bag or a laptop case in a populated area it is all most people need.

Do not buy this one if the thing goes somewhere without people. It has no GPS in it.

Hardwired Trackers

Wired into the vehicle, so charging never comes up. The ones with a backup battery matter more than they look: a thief who finds the tracker will cut its power, and a backup cell means it keeps reporting for long enough to matter.

VIM-GPS101G is the one worth understanding. Dual frequency means it receives two satellite bands rather than one, which is what keeps a position in tunnels, car parks and city streets with tall buildings either side. Those are precisely the places a single-frequency tracker drops out, and precisely where a stolen vehicle ends up.

OBD2 Trackers

Plug into the diagnostic port under the dash. Power without an install, and they move between vehicles in seconds. Both units here also carry live listening.

The trade-off is visibility. An OBD2 tracker is in plain sight in the footwell, so it suits fleet and family use where nobody is hiding anything, and it suits covert use badly.

Personal Trackers for Kids and Elderly

Built around a person rather than a vehicle, which changes what matters. SOS is the feature people buy for, and it comes in two grades: a button that sends an alert with a location, and a button that opens a two-way voice call. For a frightened child or an older person who has fallen, the second is worth considerably more than the first.

Geofencing is the other one that gets used daily: draw a zone around home or school and get told when they arrive or leave, without watching a map.

GPS Watches

The same capability in a form a person will actually keep on. That is the entire argument, and it is a strong one. A tracker in a school bag gets left in the school bag; a watch stays on the wrist.

Pet Trackers

Two different answers here and the right one depends on where the animal goes, not what animal it is. See the tag section above for the full argument, but briefly: a Find My tag works where there are people, costs nothing per month and comes two to a box. A GPS collar works anywhere with mobile coverage and costs a data plan.

Battery is the practical difference between these units. VIM-PET7 at fifteen days is in a different class from the two-to-four-day units, and battery life is what decides whether a pet tracker is still being used in six months.

The collar must break away. A cat that snags a fixed collar on a branch is in serious trouble, and it is a safety requirement rather than a preference.

Trackers With Live Audio

Eleven units combine tracking with the ability to listen to the surroundings from your phone. It is the most capable group here and legally the most dangerous thing on this page.

Where it is legitimate: your own vehicle, in your own presence. A fleet vehicle where drivers have been told in writing and have agreed, which engages the Privacy Act 2020 and the good-faith duty in section 4 of the Employment Relations Act 2000. Recovery of a stolen vehicle, working with police.

VIM-4GPS25 and VIM-4GPS30 go further again and record rather than only listen live, which raises the same issues and leaves a file. The voice recorders guide covers the audio side in full.

Assets, Containers and Door Alarms

Long-deployment units for things rather than people. VIM-4GCONT and VIM-4GCONT2 include seven and five years of service respectively, which removes the monthly plan question entirely for a container or a fixed asset.

VIM-4GPSP3 and VIM-4GPSP4 add a door alarm sensor, so they report movement of the door as well as movement of the object. On a shipping container, a shed or a trailer that is often more useful than position alone, because the thing has usually been opened before it has been moved.

SIMs, Plans and the 3G Shutdown

Every GPS tracker on this page except the Bluetooth tags needs its own SIM with a data plan, and that is a permanent cost per tracker. Any New Zealand prepay SIM with data works. The networks are Spark, One NZ and 2degrees, with Skinny and Warehouse Mobile as common prepay options.

Data use is small. A tracker reporting position is sending a few hundred bytes at a time, so the cheapest prepay plan is usually sufficient. What catches people is expiry rather than data: a prepay SIM that has not been topped up in months can be deactivated, and the first you know is a tracker that has silently stopped reporting. Check the expiry terms, not just the price.

All three New Zealand networks completed their 3G shutdown on 31 March 2026. There is no slower fallback. A tracker either has 4G coverage where it is or it has nothing, and an older 3G tracker no longer works here at all regardless of its condition.

Mistakes That Cause Returns

Reading a sleep-mode figure as a real-time one

420 days and 72 hours can describe the same device. Buy on the runtime at the interval you will actually use.

Buying a battery tracker for a vehicle you own

If it lives in one vehicle permanently, hardwire it or use OBD2. Battery trackers exist to solve the absence of power, and you have power.

Buying a Bluetooth tag for a rural property

No passing phones means no position. Tags need people.

Forgetting the SIM expiry

A prepay SIM that lapses takes the tracker offline silently. Set a reminder or use a plan that does not expire.

Hiding a magnetic tracker somewhere with no sky

GPS needs a view of the sky. Deep inside a metal chassis, in a steel toolbox or under a metal tray, accuracy collapses. Under a plastic bumper, in a wheel arch or in a boot works far better.

Assuming the magnet is enough on its own

The magnets are strong, but a corrugated road or a long trip at speed will find any surface that is not clean and flat. Clean the metal first, and check the placement after the first long run.

Buying live audio without reading the law

Listening to a vehicle you are not in is a criminal offence, not a grey area. This is the most serious mistake available on this page.

Tracking a person because you can

The Stalking and Harassment Amendment came into force on 26 May 2026 and carries up to five years. A partner, an ex-partner, an adult family member. Whose name is on the vehicle makes no difference.


Key Specs Explained

Real-time interval

How often the tracker reports. Adjustable on nearly everything here, from seconds to once a day, and the single biggest influence on battery life.

Sleep and deep sleep

Low-power modes where the tracker wakes, reports and sleeps again. Where the very long battery figures come from.

Dual frequency

Receiving two satellite bands instead of one, which holds position in tunnels, car parks and among tall buildings. On VIM-GPS101G.

Geofencing

A zone on a map with an alert when the tracker enters or leaves it. The feature people use daily rather than the one they buy for.

SOS: alert against calling

An SOS alert sends a message and a position. SOS calling opens a two-way voice call. For a child or an older person the second is worth considerably more.

Backup battery on a hardwired unit

Keeps the tracker reporting when vehicle power is cut, which is the first thing done to a stolen vehicle.

ACC and ignition detection

Hardwired trackers can sense when the vehicle is started, which gives an alert on unauthorised movement rather than on any movement.

IP ratings

First digit dust, second water. IP65 suits a sheltered mount, IP67 handles a wheel arch in a New Zealand winter.


Choose by Situation

Your own car, permanently

VIM-GPS101G hardwired for the dual-frequency reception, or VIM-GPSMINI4 for a smaller hardwired unit with a backup battery.

A car, without an install

VIM-OBD2B in the diagnostic port. Ten seconds, no tools, moves between vehicles.

A trailer, boat, machine or container

VIM-GPS4G-22 for the 20000mAh battery, or VIM-4GCONT where seven years of included service matters more than battery size. Add VIM-4GPSP4 if you want to know the door was opened as well as that the thing moved.

Something outdoors you cannot easily retrieve

VIM-4GPS-101 with its solar panel.

A fleet

Hardwired units for ignition detection and no charging. Tell drivers in writing before installation and record their agreement, because vehicle tracking of staff engages both the Privacy Act 2020 and the duty of good faith.

A child walking to school

VIM-GPSWATCH4GN or VIM-GPSWATCH4GW, because a watch stays on and a tracker in a bag stays in the bag. Set a geofence around home and school.

An older person living alone

VIM-4GPSP6 for SOS calling rather than only an SOS alert, or a watch if it will be worn more reliably.

A dog on a farm or a lifestyle block

VIM-PET7 for the fifteen-day battery. A Find My tag will not work out there.

A cat in a suburb

VIM-TAG-P9, two tags and two breakaway collars for $77, nothing per month.

Keys, a bag or a laptop

VIM-TAG at $39, or VIM-TAG-A1 for two on keyrings.


Frequently Asked Questions

Do GPS trackers need a SIM card?

Every one except the Bluetooth tags, and each tracker needs its own with a data plan. Any New Zealand prepay SIM with data works.

How much data does a tracker use?

Very little, a few hundred bytes per report, so the cheapest prepay plan is usually enough. Watch the expiry terms rather than the data allowance.

Will my old tracker still work after the 3G shutdown?

No. All three New Zealand networks completed their 3G shutdown on 31 March 2026 and there is no fallback.

What is the difference between a GPS tracker and a Bluetooth tag?

A GPS tracker knows where it is and reports over the mobile network. A tag does not know where it is and waits for a passing phone to report it. Tags are excellent where there are people and useless where there are not.

How long does the battery last?

Anywhere from 48 hours to 420 days depending on the unit and, far more importantly, on the reporting interval you set. Sleep-mode figures and real-time figures are different numbers.

How accurate are they?

A few metres in the open. Accuracy degrades under heavy tree cover, in tunnels and between tall buildings, which is what dual frequency on VIM-GPS101G addresses.

Can I hear what is happening as well as see where it is?

Eleven units support live audio. Before buying one, read the legal position: listening to a conversation you are not part of is an offence carrying up to two years.

Can I track my own car if someone else drives it?

Tracking a vehicle you own is generally lawful. Tracking a person is a different question, and if the vehicle is effectively that person's, the tracking is of them. Tell them.

Can I track my employees' vehicles?

Yes, with disclosure. Tell staff in writing what is tracked, when, and who sees it, and record their agreement. This engages the Privacy Act 2020 and the good-faith duty in section 4 of the Employment Relations Act 2000.

Can I put a tracker on my partner's car?

No. This is the question that most often ends badly. The Stalking and Harassment Amendment came into force on 26 May 2026 and carries up to five years. Whose name is on the registration does not change it.

Where should I hide a magnetic tracker?

Somewhere with a view of the sky. A wheel arch, behind a plastic bumper, in a boot. Deep inside a steel chassis or a metal toolbox and accuracy collapses.

Is there a monthly fee to Securitylab?

No. You buy the tracker and supply your own SIM. The only ongoing cost is the mobile plan, and the Bluetooth tags do not even have that.
