Police arrested a 23-year-old man and 24-year-old woman near Dargaville on Thursday after a car arrived at a house but fled after spotting police.
After a 15-minute chase, in which the driver recklessly travelled at high speeds, road spikes were used to slow it before a police vehicle was used to eventually stop the vehicle. A firearm was allegedly located inside.
A third person was located in West Auckland.
McIntosh, a father of one, was taken to Auckland Hospital in a critical condition but died on Sunday, surrounded by family and friends, after his life support was turned off.
He was described as a dearly loved father, son, brother and grandson, who would do anything for anyone.
McIntosh's family allowed medical staff to take his organs to help save others.
He would be remembered for his sense of humour and generosity, and someone who was loved by all and would help anybody out.
"That's why as a family we made the decision to donate his organs. He will be helping a lot of people with his organ donation," his aunt, Andrea McIntosh, told the Herald.
