Is It Legal to Track a Phone in New Zealand?

If you suspect a partner is cheating, one thought crosses a lot of people’s minds: can I just track a phone and know for sure? It is one of the most common questions we are asked, and there is a lot of nonsense online about it. So let’s be straight about what is actually possible, what it means for your own privacy, and where the law sits in New Zealand.

Can someone really track a phone remotely?

Short answer: no, not out of thin air. Despite what the paranoid corners of the internet suggest, nobody can secretly pinpoint your phone’s location remotely without some form of access first. The idea that a stranger, or a jealous partner, can tap a few keys and follow you around a map is the stuff of films, not reality. That level of remote tracking belongs to state agencies with serious resources, not the person sitting across the kitchen table.

What actually happens in the real world is far more ordinary, and it always comes back to one thing: access.

So how do people actually track a phone?

In practice, tracking a partner’s phone almost always requires physical access to the device, or access to the account behind it. The common methods are:

• Installing a location-sharing app like Life360, or a purpose-built tracking or “stalkerware” app, then hiding it
• Turning on Find My iPhone or Google’s Find My Device and sharing the location back to themselves
• Enabling location sharing quietly in Google Maps
• Simply being logged into the same Apple ID or Google account, which can share location with no app installed at all

That last one catches a lot of couples out. If you share an account, one of you may be able to see the other’s location without anything being deliberately set up. It is worth knowing, whichever side of the worry you are on.

Is it legal to track a phone in New Zealand?

This is where people get themselves into real trouble. Getting into someone else’s phone to install tracking software, without their authorisation, can breach the Crimes Act 1961, which covers accessing a computer system, and a modern smartphone counts, without authority. Covertly intercepting someone’s private messages or calls engages the interception provisions of the same Act. And the Privacy Act 2020 governs collecting information about an identifiable person, which is exactly what covert tracking does.

The uncomfortable truth for anyone tempted to do it themselves: evidence gathered this way is often worthless, and worse, it can expose you to criminal liability or a privacy claim. You can end up in a far weaker position than the person you were trying to catch out. What feels like taking control can quickly become the thing that undermines your own case.

What if you think someone is tracking your phone?

If you are the worried one, and you suspect a partner or ex has set something up, you are not powerless, and there are sensible checks you can make:

• Review your location sharing settings in Google Maps, Find My iPhone and Find My Device, and turn off anything you did not set up
• Check who is signed in to your Apple ID or Google account, and change your passwords
• Look for unfamiliar apps you do not remember installing
• Watch for signs like your battery draining unusually fast or the phone behaving oddly

For clear, plain-language help securing your devices and accounts, the NCSC’s Own Your Online is an excellent free New Zealand resource. And if this tips into something more serious, controlling behaviour, monitoring or harassment, Netsafe has specific, confidential support for technology-facilitated abuse. There is no shame in reaching out to either.

Tempted to do it yourself? Here’s why you shouldn’t

We understand the pull. When you are worried and want answers, rigging their phone can feel like the fastest way to know. But as above, it can put you on the wrong side of the Crimes Act and the Privacy Act, and the “proof” you gather that way is usually useless and can be turned against you. You risk becoming the one in trouble, over someone else’s behaviour.

There is a lawful way to get answers, and it is worth being clear about what that actually means, because it is not simply doing through us what you cannot legally do yourself.

How does a licensed investigator do it lawfully?

A licensed private investigator does not hack phones, plant trackers on vehicles they have no right to, or read someone’s private messages. That is not what this is. What we do is lawful physical surveillance, discreetly observing and documenting what someone actually does, and, where it is appropriate and legal, vehicle tracking, all within clear rules, to establish the facts where there is a legitimate reason to do so, for example in relationship property or family matters. The evidence stands up precisely because it was gathered properly.

Physical surveillance is the real skill here, and it is a world away from spying on a phone. It is trained, experienced people watching, following and recording lawfully, producing evidence that holds up rather than evidence that lands you in trouble. It is also something an amateur simply cannot do well, or safely, which is exactly why it is a job for professionals.

It also means being honest with you about what we will and won’t do. A reputable investigator assesses whether there is a proper basis for the work before taking it on. We are not here to help anyone monitor or control a partner, and we will say so. What we offer is a lawful, professional way to find out the truth when you genuinely need to, not a discreet route around the law.
