Two people have been found dead at a home in the Wellington suburb of Roseneath.
Detective Inspector Haley Ryan says about 10pm Monday night, police received a request for a welfare check for a concerned family member who had not heard from their loved ones.
When officers arrived, two people were found dead.
"I want to provide assurance that there is no ongoing risk to the Roseneath community," Ryan said.
RNZ understands the victims were a British couple.
A police car could be seen on Palliser Road and police say they will have an increased presence in the community.
A person RNZ spoke to said that the car had been in the area since at least 8am.
Residents at a nearby property told RNZ they heard "really loud bangs" last night, but they believed they did not sound like gunshots.
A scene examination was under way.
Police staff could be seen coming and going from the home which looks over Oriental Bay and downtown Wellington.
Officers have also been speaking to neighbours.
