Police are promising to be out in force this weekend, with thousands of sport fans expected in the city.
Senior Sergeant Phil McDouall has a simple message for those attending matches at Forsyth Barr Stadium this weekend: ''Behave yourself.''
Sixteen officers were rostered to work at the stadium for the Highlanders v Chiefs encounter tonight, and a similar number would be at the Warriors v Brisbane clash tomorrow night.
Officers would be supporting security staff, while additional staff would be rostered through the night to monitor ''after-match activities''.
Snr Sgt McDouall said people should make transport arrangements, such as nominating a sober driver, and he warned a specialist traffic unit would be out to pull over any drink-drivers.
Sports fans were also advised not to turn up intoxicated to matches as they would be refused entry.
Anyone evicted from the ground could be trespassed from the venue for up to two years.
