A crackdown on booze-fuelled crime is behind an increased police presence in some of Auckland's most popular social spots this weekend.

Police will take a zero tolerance approach to combatting alcohol-induced criminal behaviour in recognised hot-spots including Mission Bay and Ponsonby, as they begin Operation Relentless.

More than 70 police and partner agency staff will be involved, and road checkpoints will be set up.

Last month cellphone footage of mass street brawls at various locations in the Auckland CBD went viral, and resulted in two men being hospitalised with serious injuries.

Following the fights Inspector Gary Davey said the behaviour was usual in the city, especially around Karangahape Rd and Ponsonby.

A recent investigation found three of the five most violent city areas are in Auckland, with Auckland Central West topping the list of areas with the highest number of assaults, sexual assaults and robberies in public places.

Youth and Communities Manager Inspector Mark Benefield said punters heading for a night out on the town are being sent a clear message.

"If you're coming into the city over this period and intend to frequent the city's many bars, restaurants and clubs, then drink responsibly and keep yourself and your mates safe.

"There will be zero tolerance on breaches of the alcohol ban.

"Retailers and licensees will also be reminded of their obligations with alcohol, especially around intoxication and minors."
