At the time, Counties Manukau West Area Commander Inspector Naila Hassan said it's important supporters out in public behave responsibly and with consideration for others.
"We want everyone to have fun and enjoy themselves, but most importantly we want everyone to be safe.
"We urge supporters to be respectful of the community, local businesses and residents at all times when out in public," said Inspector Hassan.
