Labour leader Chris Hipkins hasn't ruled out future help for motorists if petrol prices go wild.
Petrol costs have been a major expense for Kiwis ever since the Government ended its 25-cent fuel tax subsidy earlier this year.
There are now fears fuel prices could soar with the Israel-Hamas conflict already seeing oil prices rise.
Oil prices rose by around $4 a barrel, or about 5 percent overnight, amid fears the conflict could disrupt output from the Middle East.
It comes after experts warned that the price of 91 octane in New Zealand could reach $3.50 by Christmas.
The average price of 91 octane in New Zealand is currently $2.95 but that could be about to change.
Israel and Palestinian territories are not oil producers but the Middle Eastern region accounts for almost a third of global supply.
Experts are predicting if Iran's involvement in the conflict grows, a large stake of the world's global oil supply is at risk.
But despite this, Hipkins told AM on Tuesday there are currently no plans to ease the fuel tax.
But he didn't rule it out when questioned by AM co-host Ryan Bridge about Labour's petrol policies
"I don't have any current plans to reduce petrol tax, but of course, you can't always crystal ball gaze into the future and say never say never on things," Hipkins said.
"But that was a very expensive commitment that we made to keep our fuel prices lower."
Hipkins did use the chance to hit out at National's plans to remove the Auckland Regional Fuel tax saying Aucklanders are still going to pay.
"They're going to end up paying on their rates rather than their petrol bills. They're (National) also going to introduce a congestion charge, which they will pay that as well. I think National is being disingenuous here," he said.
"They are actually going to continue to raise the same amount of money, they're just going to raise it a different way. Aucklanders will still pay and this is typical National Party, smoke and mirrors. I think when people look at what the National Party are proposing, if they win, they're going to lose because National continue to give with one hand, but then they take more back with the other."
Auckland Mayor Wayne Brown also has concerns about campaign promises National has made that could leave Aucklanders worse off.
Brown claims there's a problem with National potentially scrapping the regional fuel tax (RFT) because revenue from that is committed to a $1.4 billion Auckland infrastructure project - the Eastern Busway - which will carry 30,000 people a day between Auckland's southeast and Panmure station.
But National's leader Christopher Luxon and his colleagues said they can work with Brown and there's no threat to the busway.
"I think we're going to have a very constructive relationship with Mayor Brown and also Auckland City in general after this election," Luxon said.
"We're committed to the Eastern Busway, which is a critical project," Simeon Brown said.
