Fuel prices across New Zealand have been climbing recently, and many drivers are starting to feel the impact.

According to recent data, the average price of 91 petrol in NZ is now around $2.97 per litre, with prices rising significantly over the past month. Diesel prices have increased even more sharply, and premium fuels like 95 and 98 are also seeing noticeable jumps.

When fuel costs rise, even small savings per litre can make a big difference over time. The good news is that there are a few simple ways to reduce what you spend at the pump.

Here’s how to find the cheapest fuel in your area.

1. How to Find the Cheapest Fuel Prices in NZs

Fuel prices can vary a lot between stations, so it pays to check before you fill up. One of the easiest ways to find the best deal is by using apps like Gaspy, which show real-time fuel prices across New Zealand.

There are also other helpful tools, including Everyday Rewards, Z App (Sharetank), BPme, and Mobil Smiles, which offer pricing info, discounts, or rewards depending on the station.

👉🏼 Instead of driving station to station comparing prices, the app shows the cheapest nearby option instantly.

2. Prices Can Vary More Than You Think

Fuel prices can differ significantly between stations – even within the same suburb.

Recent examples of some of the cheapest 91 petrol stations in NZ include:

  • Tasman Fuels Greymouth (West Coast) – around $2.69/L
  • Tasman Fuel Milford (Auckland) – around $2.92/L
  • Pak ‘n Save Wairau Road (Auckland) – around $2.92/L
  • McKeown Alma 24/7 (Otago) – around $2.93/L
  • Mokotua Service Centre (Southland) – around $2.95/L

These price differences show why checking prices before filling up can make a noticeable difference.

3. Timing Your Fill-Up Can Help

Fuel prices can fluctuate throughout the week depending on supply, regional demand, and pricing strategies.

Many drivers notice that prices sometimes rise before weekends or holidays, so filling up earlier in the week may occasionally help reduce costs.

4. Small Driving Habits Can Save Fuel

Finding cheaper fuel is one part of the equation, but driving habits also matter.

Some simple tips include:

  • Maintaining steady speeds
  • Using cruise control on open roads
  • Avoiding aggressive acceleration
  • Keeping tyres properly inflated

These habits can help improve fuel efficiency and reduce unnecessary fuel consumption.

Fuel prices change regularly across the country. Tracking trends can help you recognise when prices are rising and when it might be worth filling up sooner.

Tools like Gaspy make this much easier by showing both current prices and historical trends.

Bottom Line

Fuel prices may be rising, but there are still ways to minimise the impact. Using tools like Gaspy, checking local prices, and maintaining fuel-efficient driving habits can help keep your running costs under control.

👉🏼 A few minutes of research before filling up could save you money every week.
