Nine members of the Greasy Dogs motorcycle gang have been fined $500 each following a standoff with rival gang the Filthy Few last month.

Eleven defendants pleaded guilty to a charge of unlawful assembly when they appeared before Judge Christopher Harding in Tauranga District Court yesterday.

The nine who were fined were also ordered to each pay $132.89 in court costs. Two others have been sentenced to 40 hours' community work.

Police were alerted to tensions between the two gangs about 11.30am on February 5 after Filthy Few members wearing gang patches rode motorcycles into Matapihi - an area known to be occupied by Greasy Dogs.

After the Filthy Few members became involved in an altercation with a patched Greasy Dogs member on the roadside, members of the public called police.

The Filthy Few members rode off but were stopped a short time later riding around Matapihi.

About 3pm, about 20 Greasy Dogs members travelled to the Filthy Few gang pad at Birch Ave. An altercation followed between the two groups, during which police say some of the Filthy Few armed themselves with weapons including hammers, a spade and a baseball bat. When police arrived, the Greasy Dogs members began dispersing but 13 were arrested and charged with unlawful assembly.
