Two patched members of the Headhunters gang, as well as a prospect, have been arrested after a bust in Christchurch.
Authorities were on alert on Sunday after reports of two Mercedes driving dangerously in central Otago.
Information received by police suggested they were headed to Picton.
However, at 11.30pm both vehicles were located at an address in Christchurch, Canterbury Metro Commander Superintendent Lane Todd said.
