Police pursued the vehicle as it travelled recklessly at high speeds for about 15 minutes.
"There were multiple attempts to spike the vehicle, however it continued to attempt to evade police."
The vehicle was eventually successfully spiked on River Rd, Dargaville, which slowed the car and a police vehicle was used to bring it to the stop, damaging both vehicles.
"Two people, a man and a woman, who were both wanted for questioning in relation to the homicide investigation, are now assisting us with our inquiries," Sutton said.
A firearm was also located in the vehicle.
Sutton said police had also located a third person in West Auckland who was assisting with the investigation.
"The investigation is ongoing, and further updates will be provided in due course."
