Four spectators have been arrested and charged for breaching the Act by entering, or trying to enter, the field of play during matches.
Ms Manderson, Operation Cricket World Cup national commander, said anyone who threw objects onto the field or tried streaking would receive "no tolerance" from police.
The superintendent said a hard line on boozing had kept antisocial behaviour at bay.
"We have been impressed with the responsible attitude to alcohol consumption from the majority of spectators."
She said the introduction of the Sale and Supply of Alcohol Act in December 2013 proved salubrious for all local World Cup venues.
The superintendent said police had now completed their preparations for the cup's knockout phase.
"We have been impressed with the way New Zealanders have supported their own team and also clapped and cheered our guests from all around the world," Ms Manderson said.
"The passion and flamboyance of the international fans has been infectious and Police have loved being part of the tournament," she added.
The maximum penalty for breaching the Major Events Management Act was a $5000 fine and up to three months in jail.
New Zealand play the West Indies in a quarter-final in Wellington tomorrow.
On Tuesday, South Africa will play the winner of that match in a semi-final at Eden Park.
