A body has been found in Wattle Bay, Manukau Heads, police say.
The body was found by a fisherman and police alerted just after 5pm.
Police are still on their way to the scene and it was too early to say if the body was that of a 52-year-old fisherman who went missing a week ago, a spokeswoman said.
"However, police have notified his family of this development.
The formal identification process will begin after the body is removed tonight, she said.
