Two men have been charged with murdering Auckland gang leader Kevin Weavers.
A businessman, aged 45, and an unemployed man, 53, were arrested in joint police raids on properties in Auckland and Whangarei yesterday.
Weavers, president of the Auckland chapter of the Highway 61 motorcycle gang, was found with stabwounds at the gang's Manurewa headquarters on September 27.
Police said the two men were associated with a gang, but would not say if they were members of Highway 61.
About 50 police officers, including armed offenders squad members and the specialist search group, arrested the 45-year-old man at a $1 million rural property in South Auckland.
Police said a small amount of pure methamphetamine was found at the house.
Detective Senior Sergeant Mark Gutry said the murder investigation had recovered guns and knives which would be sent for forensic testing. He said the arrests followed intensive inquiries involving many different gangs.
"It's been a difficult inquiry. We've had some co-operation with the gangs. They've certainly spoken to us but there is a lot more we need to do."
Mr Gutry did not rule out more arrests.
He said the two men had surrendered without incident when police arrived at their respective addresses to execute search warrants at 6am.
Nothing specific had triggered the raids: "We had been working throughout the week and once we were in a position to have sufficient evidence to make arrests we set the operation up."
Police had told the Weavers family and Highway 61 gang about the arrests, Mr Gutry said.
Two Highway 61 members and two others were arrested last week on firearms and drugs charges after a search of the gang headquarters and police now have a yellow Toyota Landcruiser seen outside at the time of the murder.
