A tanker will arrive on Auckland's waterfront on Sunday night with more than one million litres of jet fuel.
It is another measure to help Auckland Airport after a leak was last week discovered in the pipeline that carries jet fuel to the airport from Marsden Point refinery in Northland.
Fuel restrictions have been relaxed at Auckland Airport as airlines are now permitted to use 50 percent of their normal jet fuel supplies, but the tanker, Matuku, will likely ease the pressure further.
The damaged pipeline's temporary shutdown for repairs has led to more than 100 flights being cancelled.
Matuku will offload 1.5 million litres of jet fuel and 5.5 million litres of diesel when it reaches Wynyard Wharf on Sunday night, Radio NZ reported.
Fuel industry spokesperson Andrew McNaught says it will take around 24 hours to discharge the fuel.
"We want the product to settle, these are going into chemical tanks," he said.
He said it was the first time the process had been done, so they needed to be sure it was safe.
The fuel should reach the airport by Tuesday next week.
Energy and Resources Minister Judith Collins said on Friday that repairs to the pipeline were coming along well and should be completed before school holidays start on 30 September.
