The country's four main petrol companies raised the price of petrol on Tuesday by five cents a litre.
Shell, Caltex, Mobil and BP are now selling 91 unleaded petrol at 163.9 cents a litre.
BP has also increased the price of diesel by three cents to 104.9 cents per litre.
Spokespersons for BP and Shell say the rise in the value of the New Zealand dollar has not been enough to offset the increase in the international price of refined fuel.
Gull is keeping the price of 91 unleaded petrol at 157.9. Retail business manager Graham Stirk says the stability of the dollar is allowing the company to hold prices for now, and watch for developments in the international market.
The AA says petrol and diesel prices are unlikely to change dramatically in coming months.
AA policy analyst Mark Stockdale says the prices reflect the international market, which is relatively stable.
Mr Stockdale says companies that have not raised diesel prices are likely to do so because their cost have risen internationally.
