Major petrol station owner Z Energy has raised the price of petrol by 3c a litre.
The fuel company announced via Twitter it has also raised diesel by 2c a litre, citing "increased products costs".
Z Energy's Sheena Thomas told onenews.co.nz the increase is due to rising costs for crude and refined petrol and diesel prices on the international market.
"To give you some background, in NZD terms, 91 has gone up over
$11 since the last price decrease on 25 June, and diesel has gone
up around $8," she said.
"Brent crude has also gone up by about $US12 since the 25th and is now sitting at around $US100."
BP told onenews.co.nz that it has followed Z's lead and matched its 3c and 2c rise.
Jonty Mills, a spokesperson for BP said the prices are up "on the back of consistent increases in the cost of refined products in the last week".
Graham Stirk from Gull told onenews.co.nz its petrol prices will stay on hold for the next 24 hours and will review its position in the morning.
Gull is still undercutting its big four competitors with prices for 91 at 192.9 at manned stations and 189.9 at unmanned stations.
For diesel, the price at a Gull manned station is 136.9 and at
an unmanned station, 133.9.
