Senior Kawerau Mongrel Mob member Tahu Kingi's funeral cortège sparked an armed riot between his gang's supporters and Black Power opponents as his body was being taken to Whakatane's crematorium.
As a result six Black Power members are on trial in the High Court at Rotorua before a jury of five men and seven women.
They are: Benjamin Biddle, Stallone Harawira, Whitu Taipeti, Codie Taitapanui,
Te Reneti Tarau and Taumata Tawhai.
With the exception of Taipete they are charged with rioting, participating in an organised criminal group, unlawful possession of a firearm, using a firearm against a law enforcement officer, and discharging a firearm with reckless disregard for the safety of others.
They denied all counts when the trial opened on Monday afternoon.
Taipete has pleaded not guilty to the firearms-related charges, having earlier pleaded guilty to the rioting and criminal group charges.
Opening the Crown's case today prosecutor Richard Jenson painted a picture of a rolling riot in January last year that saw firearms loaded and brandished, shots fired by both gangs, police being shot at, missiles thrown, slogans chanted and taunts exchanged as the cortège of at least 150 vehicles carrying an estimated 300 mourners moved towards the crematorium.
The Whakatane area is considered by Black Power to be in its territory.
The jury was played videos shot by news media, civilian witnesses and a police officer of various stages of the riot as the Mongrel Mob passed through Whakatane's outskirts.
