A man was arrested in relation to the latter incident but the officer who was hit last weekend is still off work and police haven't found the offender.
Clashes in Otahuhu erupted earlier in the month with hundreds of Tonga and Samoa supporters, some armed with weapons, brawling on public streets. Dozens of arrests have been made following Saturday night games since.
The brawls were so vicious some fans gave up their tickets, including Tongan community leader Salote Heleta Lilo, who said she didn't feel comfortable attending Samoa-Tonga matches.
Counties Manukau East Area Commander, Inspector Wendy Spiller, said "violent and cowardly behaviour" against "hard-working" police staff wouldn't be tolerated.
"The last thing (police) deserve is to be attacked or harmed."
An alcohol ban in place around the Otahuhu Town Centre would be "strictly enforced," she said.
"We want people to keep themselves safe. People acting recklessly and putting themselves and others at harm by riding on vehicles or setting off fireworks in crowded areas will not be tolerated."
Significant congestion will see detours in place in the town centre and drivers are asked to consider alternative routes. Fans are also asked not to block streets, which can prevent emergency services from getting through.
