An investigation is underway after a Navy vessel struck rocks on its way back from Waitangi.
The navy launch VIP took on water after hitting rocks off Tutukaka, Northland, about 7am, a rescue co-ordination centre spokesman said.
The three crew members on board were all safe and had managed to get off the vessel.
The navy vessel HMNZS Manawanui was on its way to assist.
The Navy said the damage is being assessed, however the fuel tanks have not been compromised as the damage is to the forward section of the boat, and the fuel tanks are in the aft section.
