"He had respiratory problems, but I believe it was the shooting that killed him," he said.
According to police several shots were fired from a car, hitting the shooting victim in the legs and at least one house.
Northland criminal investigations manager Detective Inspector Kevin Burke said he believed the incident was gang-related. Police were working to establish exactly how many people were involved, and which gangs they were affiliated to.
He believed 10 to 15 people had been involved, both on the street and in the car.
The house, or houses, hit by bullets were 20 to 50 metres away and had no connection to the shooting.
No one in the houses was hit.
Detective Inspector Burke said the firearm had not been recovered, but it was believed to be a high-calibre sports rifle.
Seven detectives from Kaitaia and the Mid North were working on the case, along with ESR crime scene specialists and a firearms expert from Auckland.
They had spent Friday interviewing witnesses and examining the scene where the altercation took place and Mr McLeod's house.
He issued an appeal for witnesses, or anyone with information about the incident, to call the Kaitaia police station on (09) 408-6500, or, anonymously call Crimestoppers on 0800 555-111.
Detective Inspector Burke did not believe there was any connection between this incident and the last serious gang incident in Kaitaia, the killing of 35-year-old Lee Rata outside a wedding party on Bonnetts Road, just a few hundred metres from Archibald Street, on New Year's Eve.
That attack was believed to have been sparked by tensions within Mongrel Mob factions. Three men and a woman, all from Moerewa and with links to the Mongrel Mob, have been charged with murdering Mr Rata and are currently in custody.
