Lower Hutt police have interviewed the woman victim of a home invasion in Stokes Valley on Wednesday night.
Police say four masked offenders kicked in the door of the Amundsen Grove house, shooting a man in the upper thigh and striking the woman on the head with the butt of a gun.
A team of 10 detectives worked throughout the night and Thursday, interviewing neighbours and witnesses and conducting a scene investigation, which has now been completed.
Detective Senior Sergeant Ross Levy says they have also spoken to the woman occupant of the house and while they have some lines of inquiry, they are yet to establish the identity of the offenders, or their motive.
He says the woman required stitches after being hit on the head three to four times and the man is still in Wellington Hospital after surgery to his thigh.
Police still want the public's help over the movements of a red, Mazda Astina four-door lift back believed to have been used in the attack.
The car was stolen from the Westpac Stadium carpark during business hours on Thursday, and found burnt out in the carpark of the Taita Bowling club late that night.
