The police officer in charge of the homicide inquiry into an execution-style shooting of David Rawiri Kuka says he's determined to find his killer with the public's help.
Detective Inspector Lew Warner said after extensive inquiries over the past three months it is now believed the 52-year-old's "murder was a case of mistaken identity".
Warner said police believed Kuka, who was shot at his Gate Pa home on February 11, was not the intended victim.
Kuka was found with a serious head injury at his Wilrose Place home that night and died soon after emergency services arrived.
Emergency services were called about 10.40pm and he was pronounced dead at 11.15pm.
"Sadly Mr Kuka was shot execution-style, and we believe this was a premeditated and cowardly act," Warner said.
"Our extensive inquiries found there was no reason for David to have been targeted in this way," the officer told the Bay of Plenty Times last night.
"We know that David was a quiet man, who kept mainly to himself, working at a shop on occasion and carving items for family and friends," he said.
Warner said he was not prepared to reveal the exact weapon used or more details about the execution-style murder.
Police were keeping an open mind as to whether more than one offender was involved in his killing, he said.
Warner said police are appealing for further information about Kuka's death.
"I believe that the community can help us get answers for his family. Someone will know something and can help us bring his family some sense of closure."
