Zane Samuel Hiko has been named as the diver who died after getting into trouble on the Māhia Peninsula yesterday afternoon. He was diving at Blacks Reef.
Hiko, from Wairoa was 36-years-old.
Emergency services were called to the incident at Mahia Boating and Fishing Club about 10.30am.
"The diver was taken out of the water by diving buddies on to a boat, and taken to the nearby boatramp where they were met by emergency services for first aid," a police spokesman said.
Wairoa Mayor Craig Little said it was "really sad".
"I really feel sorry for the family ... We hate losing such a young person with so much future ahead of them."
"Being Wairoa, everyone knows everybody and it will probably affect a big chunk of the community."
