The major New Zealand city where you'll find 91 unleaded petrol at $2.037 a litre

Fuel prices around New Zealand have been climbing to heights not seen since before the pandemic recently but Hamilton boasts the cheapest petrol avaliable.

Data from the Ministry of Business, Innovation and Employment shows since 2015, the price of fuel has continued to rise with pre-pandemic prices at $2.41 a litre before taking a dip as demand plunged.

This week, according to fuel price observation app Gaspy, the average price around New Zealand for unleaded 91 is $2.24 a litre - an increase of 9.05 cents (4.21 percent) in the past 28 days.

In the same time, unleaded 95 has jumped 8.5 cents (3.55 percent) to $2.42, diesel has increased $7.19 cents (5.05 percent) up to $1.49 and unleaded 98 increased 11.83 cents (4.94 percent) up to $2.51.

Of major cities Auckland, Hamilton, Wellington, Christchurch and Dunedin, Hamilton had the cheapest petrol available at New World Te Rapa, at 11am on Monday morning according to Gaspy. Their price was $2.037 a litre of 91 and a few other stations offer petrol at $2.07 a litre.

Wellington boasted the second cheapest but there were more stations offering fuel at that price - $2.087. You'll find it at Pak'nSave Petone and New World Hutt City, Pak'nSave Hutt City.

In Christchurch 91 can be found for $2.089 at Allied Rolleston followed by $2.096 at NPD Ferry Road and NDP Darfield.

Dunedin's cheapest 91 is at NPD Andy Bay and NDP Green Island at $2.136.

In the Auckland area, the cheapest price for 91 was $2.167 which can be found at Gull Rosebank East, Gull Speedlane Rosebank, Pak'nSave Botany and Pak'nSave Papakura.

Gull general manager Dave Bodger told Newshub previously he has seen the price increases reflected across his stores.

"There's several factors in there, the price of carbon, Kiwi dollar and international prices are marching upwards," he said.

However, Bodger said demand is expected to increase in the coming months as other countries around the world ease COVID-19 restrictions.

"With restrictions say, in the UK easing on the 19th of July people are going to be more mobile, people will drive their cars more, they will go on holiday more and likely that will increase demand."
