More motorists are likely to be affected by the Auckland fuel crisis, with fliers also set to be increasingly affected.
The number of Z Energy stations in Auckland which have run out of 95 Premium has risen to 13, from four earlier on Tuesday - meaning almost a fifth of stations are affected.
And more international flights out of Auckland could get cancelled due to the jet fuel crisis, according to Minister of Energy and Resources Judith Collins.

Ms Collins wouldn't confirm how many flights might get cancelled, instead saying that Air New Zealand would make its own announcement.
Air New Zealand told Newshub some long-haul flights would be refuelled in Wellington in an attempt to avoid further cancellations.
The first of those flights would be on Tuesday afternoon, with an empty plane sent down to Wellington to refuel, then returning to collect its passengers.
Meanwhile Government officials have been warned not to make any "non-essential" air travel in and out of Auckland, MBIE's chief executive Carolyn Tremain said in a statement.
"With the pressure on aviation fuel supplies, it is prudent the public sector does what it can to help the airlines and the fuel suppliers meet the challenges of the situation," she said.
With the pipeline out of action, fuel is currently being trucked in from Marsden Point and Mount Maunganui. The Government is also looking at the possibility of bringing fuel in by ship, to Wynyard Wharf, Ms Collins said.
"The idea is to see whether or not that's viable," she said.
The leak, caused by a digger 8km south of Marsden Point oil refinery in Northland, was discovered last Thursday, and this week was expected to affect about 2000 travellers a day as jet fuel is rationed.
Ms Collins said there'll be a review once everything is sorted.
"The big focus on my mind is getting through it first, and then looking at what went wrong, how it went wrong, how it could be improved, how we could be better prepared for contingencies like this or other ones in the future," she said.
More than 30 flights, including 12 international trips, were cancelled on Tuesday morning.
It is believed the damage could take up to two weeks to repair.
