"It should be remembered that people who become intoxicated often become victims.
"Some become offenders. Look after yourselves and others."
"We want supporters and other visitors to the city to enjoy themselves and have a good time, but we also want to ensure they keep themselves safe," Banks said.
Police advised people watching the game in the city to think about their travel plans now.
Fans should leave plenty of time to get into the Westpac Stadium, whether they're travelling by public transport or car.
But he reminded people if they were having a drink before going to the stadium to ensure they don't take their cars, he said.
"It is expected that the stadium carpark will be sold out, so those who do not have a pre-booked parking space there should not attempt to enter the stadium driveway on the off-chance," Wellington road policing district response manager Senior Sergeant Richard Hocken said.
"This area quickly overloads if unnecessary turning movements are added to the intersection."
The best drop-off location is Thorndon Quay, to access the Fran Wilde walkway from the spiral, he said. Motorway traffic should use the Murphy St off-ramp, and northern suburbs use Hutt Rd and Thorndon Quay.
Taxis would not be allowed entry to the stadium after 6pm.
Taxis and shuttle vans from the city would be directed, as usual, to Bunny St (Railway Station), and Thorndon Quay was the best option from the north.
Disabled patrons should also head to the Thorndon Quay spiral as the mobility vehicles were based there for the trip along the walkway.
Patrons on the port side of Waterloo Quay should use the overbridge as the ground level pedestrian crossing is shut.
