“Allowing passengers to lean out of vehicle windows, ride unrestrained, or travel in unsafe positions creates a significant risk of serious injury or death,” he said.
“Drivers are legally responsible for ensuring passengers are transported safely.”
“Similarly, loud external stereo systems and excessive horn use can create unnecessary disturbance for the wider community and may result in infringement notices.”
Gillbanks said police welcomed celebrations of cultural heritage and sporting competition, but they had to be carried out “safely and within the law”.
He warned that unsafe behaviour would “continue to attract enforcement action”.
Following the parades, police carried out a separate operation in Mount Maunganui targeting motorists accelerating aggressively along Main Street, excessive vehicle noise and other poor driving behaviour.
Further infringement notices were issued, including for driving and vehicle noise offences.
Police said one offence detected was operating a vehicle in a manner liable to cause annoyance, which carries a $600 fine.
The warning echoes a message from Auckland police urging fans to celebrate responsibly.
“Keep celebrations away from open roads and intersections. Flags can fly freely outside your vehicle, but all passengers must remain safely inside,” said Superintendent Riki Whiu.
Despite the safety concerns, excitement has been building across Auckland, where Samoan and Tongan flags have dominated streets, shopfronts and vehicles in recent weeks.

In Ōtāhuhu, Bargain House owner Gary Wang told the Herald his store had sold nearly 1000 Samoan and Tongan flags in just two weeks.
“Very busy,” Wang said, adding that Tongan flags had been particularly popular.
Proud Tongan supporter Mele Finau said the celebrations were a chance for Pacific communities to reconnect with their roots.
“I think it’s a great way for us to show our pride in our country, especially living away from the islands. It’s our way to connect back to our motherland.”
Police have also joined in the festivities, with an Auckland officer going viral last month after dancing alongside Samoan supporters in a Henderson shopping centre carpark.
The officer was filmed waving a Samoan flag and dancing with fans at WestCity Waitakere, with the TikTok video attracting more than 260,000 views in a day.
