Update, 1pm:  Police are continuing to monitor the movements of gang members travelling south towards Foxton ahead of funeral proceedings for William Hines.

This morning, Police established checkpoints on Marua Road in Ellerslie, as the procession were preparing to depart, says Assistant Commissioner Mike Johnson.

"A large number of Police were deployed to the checkpoints prior to the group leaving Auckland.

"Several infringement notices were issued and one person failed an alcohol breath screening test," says Assistant Commissioner Mike Johnson.

The Police helicopter, Eagle, has been deployed to monitor movements through the roading network and to provide support during this operation in other Police districts.

"Our expectations on behaviour have been made clear, and any unlawful or unsafe activity will not be tolerated."

Given the volume of traffic heading south, Police are advising motorists that there may be some disruptions in parts of their journey.

"We have deployed extra staff to support this operation both on the roads and for its duration," says Assistant Commissioner Mike Johnson.

"Our focus is to try and mitigate any disruptions as much as possible.

"The safety of the public going about their business is our priority, and we urge anyone who finds themselves in a position where they do not feel safe to contact Police."

Mike says while police will act on any unlawful activity where they can safely do so, they would still like to hear from anyone who may witness any offending taking place.

Earlier, 11am:  Police will be highly visible across parts of the North Island in the coming days to monitor the movements of gang members, ahead of funeral arrangements for William Hines.

Assistant Commissioner Mike Johnson says additional resources will be deployed to target illegal behaviour and to mitigate disruption to the public as much as possible.

Police anticipate these movements to be between Auckland and Foxton.

It is also anticipated that other groups will head north to Foxton from southern regions.

Assistant Commissioner Johnson says Police have anticipated this event occurring for some time and have been making arrangements accordingly.

“Our planning is well advanced, and Police have been engaging with various parties so we can ensure expectations are clearly set on the behaviour that will be tolerated on our roads.

"Police will have increased staff deployed on the roading network across these regions, and we anticipate checkpoints to be established in some areas to ensure those taking part are adhering to the law," says Assistant Commissioner Johnson.

“Our expectations are very clear around no tolerance for unlawful activity that puts the wider community at risk."

Police say they will take enforcement action where necessary and provided it is safe to do so.

"We will also have the ability to follow up on any other reported offending so we can hold those involved to account.

“Community safety is paramount for Police.”

Police are conscious that additional traffic on the roading network may mean some delays to travel.

“Anyone who might be concerned for their safety, or who witnesses illegal activity should contact Police as soon as possible,” says Assistant Commissioner Johnson.
