About Whangamumu Reef
Whangamumu Reef is a boat-dived Northland reef with a shallow top, small caves in the shallows, and kelp-covered boulders dropping away below. The site is known as a very fishy dive, with schooling reef fish and larger residents tucked under the rocks. It works best as a guided day dive where local point choice and sea state shape the plan.
