The investigation has been underway after the man was found critically injured at a property on Waikerikeri Road in the early hours of 22 May.
He sadly died at the scene.
Detective Inspector Rhys Johnston, of Northland CIB, says a scene examination is ongoing at a property on Waikerikeri Road.
“A team of 15 investigators are working on the enquiry, with Northland receiving support from other Police districts and from ESR scientists,” he says.
“Police want to assure the community that no other persons are being sought in relation to this matter.”
A 73-year-old man, who arrived the Kaikohe Police station on Wednesday night, has been remanded in custody on a range of unrelated charges.
He will reappear in the Kaikohe District Court next month.
Enquiries will continue into the 77-year-old man’s death.
“A post-mortem examination is expected to be conducted on the victim Saturday,” Detective Inspector Johnston says.
