No one was injured in the shootings, but some of the damaged homes included people who were inside at the time and neighbours of the intended targets, authorities have said.
Police said more than two dozen people were believed to have been involved in the shootings, arriving from as far away as Picton after organising a meet-up via a Facebook Messenger group.
It appeared that high-powered semi-automatic firearms were used in the shootings, Justice Grant Powell said at Crawford's sentencing, describing the group as having felt "they were entitled to storm through communities in Ōtara, shooting wildly and recklessly as if they owned the place". He referred to the 2020 shootings as a precursor to the "reign of terror" in Auckland earlier this year due to rivalries between the two gangs.
Others have pleaded not guilty and await trial.
