Best Fuel Price Apps in New Zealand 2026: Gaspy, Brand Apps and Discounts Compared

Fuel apps at a glance

Start with Gaspy to see which station near you is cheapest. Then add the app for the network you pass most: Z's app gives a daily discount and a bigger one on Wednesdays, bp's app works with Woolworths' Everyday Rewards card, and Foodstuffs' Club+ turns a supermarket shop into a discount at Z and participating Caltex sites. Waitomo and Gull reward you through in-app credit and promotion days rather than a fixed cents-per-litre discount.

Discounts are capped per fill, usually at 50 or 100 litres, and the schemes can change their amounts at short notice. Check the terms in the app before a long drive rather than relying on last month's offer.

1. Gaspy: best for finding the cheapest station

Gaspy is a crowd-sourced price map run by Hello World Limited. Its users enter the price shown on the pump, other users confirm it, and both earn Spy Coins when a price is confirmed. Gaspy's help page says updates are limited to stations near you because of past misuse, which keeps prices honest but means a remote station can show an old figure.

You can tell the app which discounts you hold, and it shows your discounted price above the pump price; the free version allows one custom discount and Gaspy Gold, NZ$1.69 a month, allows as many as you like. Favourites can send price alerts, and the map also lists EV chargers. It rated 4.0 from 773 New Zealand ratings.

2. Z Energy app: best everyday discount on a major network

Z Rewards in the Z app takes at least 6 cents a litre off every fill, up to 100 litres, and 15 cents a litre from 6am Wednesday to 6am Thursday when you scan in the app. You also earn a point for every dollar spent on fuel and Airpoints on fuel, and Sharetank lets you share a virtual fuel tank with up to five people.

It rated 4.8 from 13,568 New Zealand ratings. Z's Wednesday figure has changed before (it was 10 cents in mid-2025), so confirm it on the rewards page before you plan a fill around it.

3. BPme with Everyday Rewards: best if you shop at Woolworths

bp takes 6 cents a litre off up to 50 litres when you scan an Everyday Rewards card, and the same card earns a point per litre towards $15 vouchers. Woolworths, which runs Everyday Rewards, also issues bonus fuel discounts for qualifying grocery spends; their size changes and is not fixed in its terms. BPme links your Everyday Rewards card in the app and rated 4.9 from 34,764 New Zealand ratings.

The same Everyday Rewards discount works at g.a.s. stations, and the g.a.s. app (4.7 from 1,027) links the card there.

4. Club+: best if you shop at PAK'nSAVE or New World

Foodstuffs launched Club+ in June 2026 in place of the New World Clubcard. A qualifying spend of $1 or more at a store without its own fuel site earns an 8-cent-a-litre discount, up to 100 litres, to use at Z or participating Caltex sites within 30 days. PAK'nSAVE and New World stores with fuel on site give their own discount, which Club+ states as at least 8 cents a litre in the North Island and 4 cents in the South Island.

The Club+ app rated only 1.8 from 682 New Zealand ratings, and its terms let Foodstuffs change the discount at any time. Gull is not part of the scheme.

5. Waitomo, Gull and Mobil: best for their own networks

Waitomo's app (4.8 from 23,195) gives a spin to win credit called Moolah on fills of $20 or more, plus scratchies when your monthly spend passes set amounts; Moolah is spent in the app. Gull's app (4.8 from 17,818) unlocks pumps at unmanned Gull stations and Pay at Pump lanes and runs promotion days. Neither states a fixed cents-per-litre discount.

Mobil's app (4.7 from 10,135) earns Smiles points and pays for fuel from the car. We could not load Mobil's own rewards page to confirm its current discount, so check it in the app.

Diesel, EVs and remote roads

MBIE's diesel figure excludes road user charges. NZTA charges $76 per 1,000 km for light diesel vehicles, so add about 7.6 cents a kilometre to the pump cost when you compare a diesel campervan with a petrol car. Hire companies bill RUC in different ways; ask before you book.

For electric vehicles, PlugShare (4.6 from 4,173) maps chargers from many networks, and the Z app also handles Z's EV charging. On remote routes the cheapest fuel is the fuel you already have: DOC notes there are no fuel stations between Te Anau and Milford Sound, so fill up in Te Anau.

Where KiwiCamping fits

KiwiCamping does not show fuel prices, so it is not on the list above. What it does show is distance: a trip in KiwiCamping gives the distance and drive time for each leg between stops, so you can see which legs are long and plan where to fill up before them. A collection of saved places also shows how far apart its two furthest places are, a rough idea of how much ground the trip covers.

KiwiCamping runs on iPhone with iOS 26 or later, and its four New Zealand ratings average 3.8. To turn those distances into dollars, our fuel and distance calculator on this site does the arithmetic.

How we chose and checked

We included the price app with the most New Zealand use and the app of every fuel brand or loyalty scheme we could verify. Discounts and caps come from each company's own rewards or terms page on 20 October 2026; ratings come from the New Zealand App Store that day. Fuel prices come from MBIE's weekly monitoring table, which records board prices, not prices after discounts.

We describe each scheme as the company does. A discount or feature not mentioned here is not a claim that it does not exist.
