A fourth man, 21-year-old Nathan Scott Hampton-Burgess, was also arrested after complaints about debt collection agencies Dirty Debtors and Rapid Recovery.
All four men were charged with participating in an organised criminal group and the aggravated robbery of "William Baker" on Friday in the police sting.
Sisson was also charged with possession of three rifles - a Ruger bolt action .243, a Ruger bolt action .308 and a .22 rifle - and 650 bullets.
The senior Hells Angel was also charged with robbing a Helensville couple of a Suzuki quad bike in March and the theft of a Toyota van in September under the guise of recovering debts for clients. He was also charged with using a document headed "Warrant to Repossess" with intent to obtain property dishonestly. Sisson, who will appear in North Shore District Court today to apply for bail, is the man behind Dirty Debtors Ltd.
The debt collection firm runs a website to "name and shame" people who allegedly owe debts to clients.
Detective Inspector Grant Wormald, of the Organised and Financial Crime Agency New Zealand, said some debt collectors traded on their gang membership.
"More often than not the gangs are used to collect debts in the knowledge that people will pay up through fear and intimidation," he said.
"People should be left in no doubt that these gangs are heavily involved in organised crime and they should be wary of having any business or social dealings with them."
Anyone with information about illegal debt collection involving Dirty Debtors or Rapid Recovery can contact Detective Inspector Wormald at OFCANZ or call Crimestoppers anonymously on 0800-555-111.
