A study reveals more than 50 per cent of Kiwis keep an active eye on the price of petrol.
During May New Zealanders spent $614 million on fuel.
"Even with the recent drop in prices, fuel costs can vary hugely within a relatively small geographical area, so it's easy to see why people think it's worth keeping an eye on prices," Canstar Blue spokeswoman Emma Quantrill said.
Canstar's study of 2253 people found that 51 per cent were actively monitoring fuel prices and 75 per cent were prepared to travel further - up to 5km - to take advantage of cheaper fuel costs.
"We found that nationally, there was a huge 65 cents per litre difference in the highest and lowest prices on 91 Octane and while most of us understand shipping costs will be higher to more remote areas, the variation in local prices is more difficult to understand," Quantrill said.
