Fuel retailer BP has dropped the price of petrol by 3 cents per litre.
A litre of fuel now costs $2.03.
The company says it has now dropped prices four times in the past two weeks, which means motorists are paying 13 cents less than they were.
BPs managing director Matt Elliott says a fall in international product prices is behind the latest drop in price.
Gull has, meanwhile, dropped the price of its regular 91 octane to $1.99 per litre.
Drivers will now pay $1.99 for Regular and $2.12 for Force 10.
Diesel prices remain unchanged.
