Petrol and diesel prices both decreased from June 2026 to July 2026, according to figures released by Stats NZ this week. 

Petrol prices were down 5.7 percent, while diesel prices decreased 12.1 percent.

“Fuel prices decreased for a third consecutive month, following increases in March and April,” prices and deflators spokesperson Nicola Growden said.

“The recent declines mean prices for petrol and diesel are now below levels recorded in March, although they remain higher than in February.”

In the 12 months to July 2026, prices for these two fuel types increased – petrol was up 15.1 percent and diesel up 34.9 percent.
