This month the gang posted pictures and an update on its website about new probationary chapters opening in Dunedin and Invercargill.
''Bandidos MC New Zealand are excited about welcoming into our Great Red & Gold Nation two new probationary chapters,'' the website said regarding the ceremony held in Invercargill last month.
That post included photographs of a patching ceremony for the Southern probate gang members, which was attended by patched Bandidos members from Australia, Auckland and Christchurch.
Detective Senior Sergeant Malcolm Inglis, of the Southern District organised crime squad, said police were ''certainly aware'' members from rival Dunedin gangs had joined the Bandidos.
Dunedin motorcycle gangs include the Southern Vikings and the Road Knights.
The Bandidos have an estimated 2500 members and 210 chapters in 22 countries, including Australia, where there were 17 official chapters.
Its motto is ''We are the people our parents warned us about''.
