COLVILLE CHANNEL

The 'Colville Channel' is one of three channels connecting the Hauraki Gulf with the Pacific Ocean to the northeast of Auckland, New Zealand. It is the easternmost channel, lying between the southern end of Great Barrier Island and Cape Colville at the northern tip of the Coromandel Peninsula. The tiny Channel Island lies in the centre of the channel.
The other two channels are the Cradock Channel and the Jellicoe Channel.
