Meanwhile, the police hunt for the escaped offenders continues as Cyclone Gabrielle looms over the Auckland region.

During their search, police arrested two people over the weekend believed to be involved in the ongoing escape, however, both were arrested on unrelated charges.

On Saturday, a police operation was launched when officers were alerted to a vehicle of interest in Warkworth shortly after 2pm, the car was believed to be connected to the prisoners’ escape.

Eyewitnesses saw several police cars and a hovering helicopter on the north side of the Johnstones Hill tunnel, chasing a black SUV.

Armed Police stopped the car on State Highway 1, near Pohuehue, without any issue.

A police spokesperson said two people were arrested on matters unrelated to the escape and were helping the police with inquiries.

Earlier that day, Detective Senior Sergeant Scott Armstrong had issued a warning to anyone who may be concealing information about the trio’s whereabouts.

“Our focus remains on locating the prisoners; however, we would like to remind people that anyone who is helping these men avoid police could be liable for criminal charges,” he said.

The men at large have connections across Counties Manukau and Auckland City, police said.

Fepulea’i was in court last year over an assault on a police officer that was filmed and later shared on social media.

The incident happened on January 28 on Tāmaki Drive near Mission Bay and left the officer injured.

Fepulea’i was later charged with assault of police, resisting police, possession for supply of methamphetamine, injuring with intent to injure, escaping police custody, possession of utensils for consuming methamphetamine, theft under $500 and procuring methamphetamine.

Some of the charges related to past incidents.

Superintendent Shanan Gray made a call for anybody who witnessed the escape to contact police as soon as possible using the 105 phone service.

“This is an ongoing incident and further updates will be provided once they become available,” he said.

A Corrections spokesperson said police were informed immediately.

“We encourage anyone with information about the prisoners’ location to contact police on 111,” they said.

“Public safety is our top priority.”
