The car was seized for forensic examination. A residential Whangarei address will also be forensically examined by police and ESR.
The woman is in hospital in a stable condition.
Inspector Justin Rogers of Northland Police said, "This is a terrible crime and our thoughts are tonight with the victim. She is being supported by family members, police and Victim Support."
"I know the community will be shocked and angered by this, however I would like to reassure everyone that we have caught the person alleged to have done this, he is in custody and we are not looking for anyone else. We have put every resource available to us into this case from early this morning and I hope this arrest will bring some degree of comfort to the residents of Whangarei," he said.
Police would like to hear from anyone who saw a Blue Nissan Serena people-mover with tinted windows and silver trim below the door line in the Whangarei area, particularly around the Hatea Loop, in the days leading up to this attack. Anyone with information is asked to contact the Whangarei CIB on 09 430 4500.
