PetrolWatch

We complete weekly and monthly AA PetrolWatch reports that give an indication of fuel price changes in New Zealand.

In these reports we include overall changes to 91 Octane, 95 Octane and Diesel prices.

Running costs report

The AA compiles a yearly report on car running costs in NZ. It highlights car running costs (petrol and diesel) and shows petrol vs. diesel comparisons, and can help you identify ways to save on car costs.

How petrol prices are calculated

Fuel prices are made up in several ways in New Zealand. How do our fuel prices compare with the international oil and refined fuel prices?

New Zealand LPG pricing

There is an expectation that LPG prices should fall when petrol and diesel prices fall, but there are several reasons why this is not so.

Running cost comparison: 91 & 95 Octane

So which one should you use if you want to save money? Even after the AA tested consumption between the two fuels, the decision whether to use 91 in preference to the higher 95 octane was not as simple as it seemed.

Biofuel & environmentally friendly cars

Biofuel is a renewable fuel typically made from food crops, wood waste, or, as in New Zealand, from dairy industry by-products. Biofuel can either be petrol blended with a maximum of 10% bioethanol, or diesel blended with a maximum 5% biodiesel.
