“I was afraid that they might cause an accident,” he said.
“They were driving the opposite direction of the road, then they joined the flow of vehicles and took over both lanes and didn’t allow anybody to overtake them.”
Dashcam footage shows riders running a red light, performing wheelies, mounting the footpath and weaving in and around cars and traffic cones at a crowded intersection.
Aziz said traffic slowed to about 40km/h as drivers tried to keep their distance.
“They would speed up all at once and then slow down again just to make sure they spread all over the road,” he said.
He claimed many riders had their faces covered and no visible number plates, and none appeared to be wearing helmets.
Aziz said he saw riders antagonising another driver in front of him.
“The driver was slowing down as much as possible to avoid them and ended up going on the motorway to stay away from them, which was a smart choice in my opinion.”
Police said they were aware of informal rides planned across parts of Counties Manukau and Auckland City this weekend.
Counties Manukau Police Inspector Dave Christoffersen said they would be monitored and action taken against riders who broke road rules or engaged in anti-social behaviour.
Aziz said the behaviour left him concerned about the risk of a serious crash.
“They are jeopardising their lives first and then they are jeopardising the life of everyone else on the road,” he said.
“[The bikers] are at the mercy of how responsive other drivers are.”
He urged other motorists to remain calm if they encountered similar scenes.
“Don’t try to do anything crazy … just give them the way, there is nothing to prove, let them pass."
