The Cabinet has made no decision on ending oil exploration, documents being released today will show, with April's announcement made on the basis of a political agreement between the coalition parties.

On April 12, Prime Minister Jacinda Ardern led a group of ministerial colleagues into the Beehive theatrette to confirm news that the Government had decided it would offer no new offshore permits for oil and gas exploration, with onshore permits offered in Taranaki for as little as three years.

Although the news was delivered by ministers affected by the decision and in a forum usually used to discuss decisions made by the Cabinet, politicians made the decision in their roles as party leaders.

Today the Government will release a series of documents generated in the making of the oil and gas exploration decision, but it has already confirmed to Stuff that no Cabinet paper was created and that the Cabinet has not voted on the matter.
