The arrest comes after police were called to Thomas Rd just before 12pm yesterday, after reports a man had been hit by a vehicle which then allegedly left the area immediately afterwards.
Streets in the south Auckland suburb were cordoned off for much of the afternoon.
Armed police were posted Pukaki Rd, about five minutes down Massey Rd from the scene of the incident.
One witness saw up to 20-30 people restrained across two scenes, amid a heavy police presence of about 15-20 officers.
Another witnessed described seeing two men smashing a car on Thomas Rd.
