Can you drink the tap water in New Zealand?

Can you drink the tap water in New Zealand? Yes. In towns and cities it is treated to a national standard, monitored continuously and safe to drink straight from the tap. Buying bottled water here is, for the most part, buying something you already have.

That is the short answer and it covers almost every situation you will be in. The details worth knowing are about the edges: rural supplies, streams, and where to fill a campervan tank.

Town and city supplies

New Zealand's public drinking water is regulated by Taumata Arowai, the national water regulator, and suppliers have to test and report continuously. Auckland, Wellington, Christchurch, Queenstown and every town of any size are entirely fine.

The taste varies a little by region — some supplies are chlorinated more heavily than others, and Christchurch's water famously comes from an aquifer and needs almost no treatment at all. None of that is a safety question.

Where to be a bit careful

Two situations call for attention, and neither is dramatic.

• Small rural supplies — occasionally issue temporary boil-water notices, always signposted locally
• Untreated bore or roof water — some remote campgrounds and holiday homes; if a tap is marked not for drinking, believe it
• Streams, rivers and lakes — never drink untreated, however clear the water looks

That last one is the real one. New Zealand's backcountry water can carry giardia, a parasite that is unpleasant and takes weeks to shake. It is present in water that looks perfectly clean, because it comes from animals upstream — possums, deer, farm stock. Boil it for a minute, filter it, or use purification tablets.

Filling a campervan water tank

This is the practical bit. Your fresh water tank should only be filled from a tap marked as potable — you will see them at holiday parks, at most DOC campgrounds, at public dump stations and at many i-SITE visitor centres.

A few habits worth having:

• Use the drinking-water hose, not the one lying next to the dump station
• Fill up when you are at a reliable source rather than waiting until the tank is low
• In remote areas — the Catlins, parts of the West Coast, Fiordland — top up before you go, not after
• If a tank has stood unused for a while, run it through before drinking

Our campers come with the tank full at pickup and we tell you where the good filling points are along your route. It is one of the small things that stops being a question after the first couple of days.

So do you need bottled water?

No, and carrying a reusable bottle instead is genuinely better here. Public drinking fountains are common, cafés will fill a bottle without being asked twice, and every campground has potable water.

The one time bottled water makes sense is as an emergency reserve in the vehicle if you are heading somewhere very remote for several days. Beyond that it is expensive packaging around something coming out of the tap.

For the rest of what to expect on the road, our first-time camper guide covers the practical side, and what's included lists what comes with the camper.

Can you drink stream and river water?

Not without treating it, however clear it looks — and this is the one that catches trampers out.

New Zealand backcountry water can carry **giardia**, a parasite that causes several unpleasant days and sometimes weeks. It is present in some catchments and impossible to detect by eye, and the clearest alpine stream is no guarantee.

If you are filling from a stream, boil it for a minute, use a filter rated for protozoa, or use purification tablets. For everyday travel this rarely comes up: town supplies and most campsites have treated water.

Is the water safe at DOC campsites?

It depends on the category, and the sign will tell you.

**Serviced** campsites have treated tap water. **Standard** sites usually have a water supply, and **basic** sites may have water from a tank or a stream. DOC signposts which is which, and where water needs boiling it says so.

The practical approach with a camper: fill your tank from a town supply or a serviced site when you can, and treat anything from a tank or a stream as needing boiling unless a sign says otherwise.

Does the water taste different?

In some places, yes, and it is not a safety issue.

Christchurch draws from artesian aquifers and has some of the best-tasting tap water anywhere. Some smaller West Coast supplies taste faintly of the peat the water runs through, which is harmless. And a campervan tank that has sat for a few days will taste flat rather than fresh — run it through, and refill more often than you think you need to.
