New Zealand's Mongrel Mob is actively recruiting Maori and Pacific Islander members in Melbourne's outer suburbs, say police.
Officers are aware of the gang's activities and are monitoring them, the Herald Sun reported.
Police received reports last year of Mongrel Mob members wearing patches in Australia and the gang may now be looking to expand its drug network, Canberra-based New Zealand Police liaison officer Detective Inspector Steve Wood is reported saying.
"We have been working with the Australian police forces regarding their movements for the last six months," he told the Herald Sun.
The gang was formed in Hawkes Bay in the 1960s, and members' patch depicts a snarling bulldog with a studded collar and wearing a Nazi helmet.
