Detective Senior Sergeant Nick Poland, of Waitematā CIB, says the woman and man were known to each other.
”As such, police are not seeking anyone else in relation to this matter,” he said.
“We would like to reassure the community that this appears to be an isolated incident.”
Poland said more police would be seen in the area as they made inquiries.
A scene guard is still in place on Moire Rd.
“Police will endeavour to provide further details around the identity of the victim when we are in a position to do so,” he said.
“However, as this matter is now before the court, we are limited in providing further comment.”
Emergency services, including fire and ambulance teams, rushed to the scene late last night.
Police could be seen focusing their attention on a car in the middle of Moire Rd.
This is the second homicide enquiry launched in the suburb this week. The first, on Sunday, relates to an incident where police attended a property on Chorley Ave and found a woman dead at the scene.
