The Rangitoto Channel is an area of the Hauraki Gulf in the Auckland Region of New Zealand's North Island.

The channel is north-east of the Waitematā Harbour, and is located between the North Shore and Rangitoto Island.

[2] The channel is an important stretch of water as it is the only deep water approach to Auckland Port for large ships such as container cargo ships and passenger cruise liners.

[3] The traditional Ngāi Tai name for the Rangitoto Channel is Te Awanui o Peretū or "The Great Channel of Peretū", named after an early ancestor in Tāmaki Makaurau, who lived at Narrow Neck and kept a kākā parrot reserve on Rangitoto Island.

[4][5] The channel was visited by the Tainui migratory canoe after arriving in Tāmaki Makaurau.
