Police conducted 15 vehicles stops while the warrant was in place.
As a result of these vehicle stops, five gang members – a mix of Mongrel Mob and Black Power - were arrested and charged with a range of offences, including possession of offensive weapons, possession of methamphetamine and cannabis, driving while disqualified, and breach of bail.
Various quantities of methamphetamine and cannabis were located, along with knives and other weapons including a set of knuckle dusters with a blade attached.
Police also impounded three vehicles.
In addition to the five arrests during vehicle stops, a 24-year-old patched Black Power member was arrested on 13 September and charged with unlawful possession of a firearm, after two firearms were located at his address.
The man was remanded in custody to appear in Gisborne District Court on Monday.
Alongside the work carried out by officers in Wairoa, Tairāwhiti Police are continuing to investigate a report of shots being fired at a house on Glasgow Crescent overnight on Tuesday/Wednesday last week.
Nobody was injured in this incident, however, “the occupants of the house were understandably shaken.
