Which channel separates the North Island of New Zealand from Great Barrier Island?

Colville Channel separates New Zealand’s North Island from Great Barrier Island.

The channel lies in the northeastern part of New Zealand’s Hauraki Gulf. It is named after Cape Colville, the prominent headland at the northeastern tip of the Coromandel Peninsula. Great Barrier Island sits to the north of the channel, while the Coromandel Peninsula and the North Island lie to its south.

The passage is part of a complex coastal system containing islands, headlands, bays, and channels. Its waters connect the inner Hauraki Gulf with the Pacific Ocean and are used by commercial vessels, ferries, fishing boats, and recreational craft.

Colville Channel should not be confused with Cook Strait, which separates New Zealand’s North and South islands. It is also distinct from the Hauraki Gulf itself: the gulf is the broader body of water, while Colville Channel is one of its named passages.
