Police urged people to resist the temptation to socialise in gatherings that would breach the restrictions.
"Under no circumstances should anyone be having a party under the alert level 3 restrictions," acting Assistant Commissioner Scott Fraser said.
"Such behaviour could waste all the sacrifices made by our team of five million over the past five weeks.
"Now is not the time to be complacent and we know from the volume of people reporting these parties and gatherings, that they don't want to lose all the gains made in the collective effort to beat Covid-19," he said.
"No parties, no excuses."
Reports of mass gatherings of 10 or more people were being prioritised.
"Holding a party in the current environment is in breach of the Health Act and where appropriate enforcement action will be taken. This could be against the party hosts and the attendees," Fraser said.
Most Kiwis were acting responsibly and sticking to the rules by staying local, travelling within their region and physically distancing in public, he said.
Suspected breaches can be reported by phoning 105, contacting police online via the 105 form, calling Crimestoppers anonymously or in emergencies, calling 111.
