Police say they are keeping an "open mind" about how the person who killed Auckland entomologist Stephen Thorpe left the Blockhouse Bay area.
Thorpe was a keen entomologist, described as someone who "wouldn't hurt a fly" and had been working at an office beneath the Blockhouse Bay Tennis Club for a number of years.
He died from critical injuries late on Saturday morning.
Police previously said the person responsible left the scene on foot.
But in a statement on Tuesday, detective inspector Glenn Baldwin said the investigation team was "keeping an open mind at this point about how the offender left the area".
"If you saw something untoward, whether it's someone on foot, on an e-scooter or leaving in a vehicle we need to hear from you."
Officers were going door-to door in Blockhouse Bay as part of their ongoing homicide investigation called Operation Elba.
Baldwin said officers were maintaining an ongoing presence in the area.
"Our scene examination concluded yesterday afternoon and cordons have since been removed around the tennis club," he said.
"The Mobile Police Base has been set up in the area, and we have a number of staff working as part of an area canvass knocking on doors."
Police were still wanting to hear from anyone who has CCTV footage or who saw anything untoward leading up to, and after, 11.30am on Saturday.
"We still want to hear from anyone who saw suspicious activity."
A karakia has been held at the scene where Thorpe lost his life and it was attended by dozens of community members, said Baldwin.
"Investigators remain determined in their work to identify and hold this offender to account."
Police were asking anyone with information to contact 105 or go online, using 'Update My Report'.
