A woman's finger was nearly amputated when it became stuck in a boat's boarding ladder in the Hauraki Gulf this afternoon.
Emergency services were called to the 12m launch near Motuihe Island's Ocean Beach about 3.30pm, Coastguard Northern Region said in a statement.
"A woman had got her finger caught in a boarding ladder, resulting in a nasty near-amputation wound," the statement said.
Coastguard vessel Maraetai Rescue One was quickly on the scene with a medic on board.
The bleeding had been stemmed by the time they arrived but the woman was in severe pain.
