Plummeting oil prices have seen TAG Oil give notice it will formally relinquish its remaining Hawke's Bay exploration permit.
Billions of barrels of oil were estimated in TAG's East Coast exploration areas but with no partner forthcoming to share a costly drilling programme and the wholesale global price of oil one third of the price two years ago, TAG has walked away.
Last year it surrendered its permit area near Gisborne and the latest permit area to be surrendered includes the drill sites at Boar Hill near Porangahau and Ngapaeruru-1 east of Dannevirke.
Tararua mayor Roly Ellis said the district had been looking forward to economic development should the drilling programme enable commercial quantities of oil, but some residents would be pleased to see TAG depart.
He said whether drilling resumed "all depends on the price of oil" but the district had other development possibilities.
