Two women and a man had gone to a home to carry out a property inspection when they were shot at a rural Whangarei address today.
Work is still being done to establish what started the fire which destroyed the house in Northland where two women were shot dead this week.
The property on Whangarei's Mt Tiger Road went up in flames on Wednesday afternoon, as police were trying to negotiate with gunman Quinn Patterson.
Propertyinspectors Wendy and Natanya Campbell - mother and daughter - were shot dead and contractor Jeff Pipe was shot and injured but is now recovering at home.
Forensic staff will spend the weekend conducting a detailed search of the burned-out property.
They've found what's believed to have been a gun, next to Patterson's remains.
Police are continuing to support the victims involved and their families, as well as the police staff who responded.

"Police has received many messages of support from the community here in Northland and I would like to express my thanks for those," said Le Prou.
"It is at times like this that our community really shows its strength.
"We will work tirelessly to ensure we get answers to the questions which are being asked, and identify any steps needed to prevent a tragedy like this occurring again."
