Petrol prices have increased significantly since the start of the year. Add on the cost of living crisis, and many people find themselves stuck in a tight spot.
Fuel tax
You’re not just paying for petrol when you fill up. Most Kiwis would probably be surprised at how much of their money goes towards tax at the pump, especially since the end of the fuel tax subsidy, at the start of July.
Currently the amount of tax included in the price of a litre of petrol in NZ is:
- 70.024c – National Land Transport Fund
- 6c – ACC Motor Vehicle Account
- 0.66c – Local Authorities Fuel Tax
- 0.72c – Petroleum or Engine Fuels Monitoring Levy
On top of this you have:
- GST at 15%
- 10c extra in Tamaki Makaurau for the Auckland Regional Fuel Tax
This means that for most Kiwis, the amount of tax on a litre of gas is now around 77c, or 87c in Auckland. For more information, click here.
Why is petrol so expensive? NZ petrol price rises
The table below shows how the main port price has also increased in NZ this year. The main port price is a weekly average of retail prices in: Auckland, Hamilton, Wellington, and Christchurch.
| Petrol | Cost per litre Jan 2023 |
Cost per litre July 2023 |
Price increase |
| 91 | $2.50 | $2.81 | 12.4% |
| 95 | $2.67 | $2.97 | 11.2% |
As you can see, our petrol prices have gradually increased since the beginning of the year.
Why are petrol prices increasing?
There’s a few factors behind the rising prices of fuel this year, including:
- End of fuel tax discount
- Fuel companies were reluctant to pass on the full excise increase on July 1, so have gradually been increasing fuel prices
- Carbon costs from the NZ Emissions Trading Scheme (ETS)

So, why is petrol so expensive?
Fuel prices have risen this year due a range of factors, but the most impactful has been the removal of the fuel tax discount. The fuel tax subsidy was first introduced in March 2022, to help combat rising fuel costs caused by the war between Russia and the Ukraine. However, on July 1, 2023, the subsidy was removed, and fuel prices shot up overnight.
However, some fuel companies were reluctant to pass on the price increase to Kiwis in one hit. This has meant that fuel prices have continued to climb throughout July and into August. Ongoing uncertainty around the ETS and carbon prices has also helped keep fuel costs high.
So while overall petrol prices are now lower than July 2022’s record highs, thanks to increased taxes, at the pump, the cost of petrol remains elevated and, unfortunately, seems likely to remain so for the foreseeable future.
