Fullers is investigating the cause of a crash between two of its ferries in Auckland last night.
The Kea, which travels between Auckland and Devonport, clipped the Harbour Cat which was berthed at the ferry terminal at 5.30pm last night.
St John treated one person for minor injuries.
Fullers says the Kea had broken down earlier in the day, but had been cleared to go back into service.
It's not known if that had anything to do with the collision.
