A section of Great North Rd near Williamson Ave has been cordoned off after the incident just after 1am.

Detective Senior Sergeant Geoff Baber said the fight was "large" and began at the Grey Lynn Tavern.

The road is currently closed between Crummer Rd and Williamson Ave and could be for the majority of the morning.

"We apologise for any inconvenience this may cause," said Baber.
