The incident was captured on cellphone video.
It came amid what was a week of violent public incidents in Napier.
All police in Hawke's Bay were armed for five days as a result of the several gang-related incidents on Sunday November 17, reviewed on a daily basis.
The decision was made to cease general arming on Friday morning.
In the first of those incidents, an apparent turf war at Anderson Park, a man in his 20s was admitted to hospital with a broken jaw.
Over the next few hours a person was reportedly struck by a vehicle across town in Geddis Ave, Maraenui, a man arrived at the Napier Medical Centre with a stab wound, and a shot was fired outside the Wellesley Rd centre after patched gang members had gathered in the area.
Witnesses to Sunday's fight said there was no evidence to suggest it was gang-related.
