Police are again appealing for public help in identifying a vehicle involved in a hit-and-run in Taupō on 21 June.
A 36-year old woman, named only as Supriya, was badly injured after being struck by a white ute in Richmond Avenue.
She remains in a serious but stable condition in hospital.
The police have described the vehicle as being a double cab or King cab with rear doors.
Detective Sergeant Andy Livingstone said the driver would be responsible to their own family, the community and the victim over their decision to come forward or not.
"I would appeal to those who know where this vehicle is now and the identity of the driver to come forward to police with this information.
"We are intent on giving Supriya and her family some answers and we believe there are people who know who is responsible and can help provide those answers.
"We urge them to do the right thing and come forward to police."
Police are also interested in a white sedan which was seen in CCTV footage at about the same time as the ute.
They also want to speak to the driver of that vehicle who they say may have valuable information to share.
