Norwegian-based Statoil has told the government that it is relinquishing its oil exploration permits in the Reinga Basin.
Vice-president exploration Pal Haremo and New Zealand country manager Brynjulv Klove were in Kaitaia last week to break the news, ahead of publicly releasing it on Friday.
The company was awarded two exploration permits for the Reinga Basin, about 85 kilometres off Northland's west coast, in 2013 and 2014, Mr Klove saying that seismic data gathered over the last three years suggested that the chance of making a large oil or gas discovery was small.
"We have decided to conclude our exploration work in Northland, and return those exploration permits to the Crown," he said.
"Some may speculate that we are surrendering the permits for various reasons, but the only reason is that we see the probability as too low to justify continuing our search."
