Police are urging motorists to be cautious on the Rimutaka Hill Rd after a diesel spill this morning.
Acting Inspector Bruce Mackay said the spill reached down the entire Wairarapa-bound lane on the Wairarapa side of the hill.
It was not immediately clear how much diesel had spilled.
It was believed a truck driver had left a fuel cap off, though the truck had not been found.
Police were notified of the spill at 7.40am.
