As the festive season fast approaches police across the Bay are increasingly being called to out-of control house parties fuelled by excessive drinking.
Officers regularly come across youths wandering the streets at weekends looking for parties, and the growing popularity of social media has resulted in many a gate-crashing horror story around the world.
In New Zealand approximately one third of all police recorded offences are committed after the offender has been drinking alcohol.
"We're not out to stop people from having a good time or to stop people from having a social drink," says Prevention Manager Inspector Scott Fraser.
"The issue is excessive drinking that is leading to poor decisions, like fighting and driving drunk.Youths in particular are leaving themselves vulnerable to becoming victims of crime because they are allowing alcohol to inhibit their perception of a safe environment."
