Ms Holmes extended suppression until Friday but said "there's every chance it will be lifted on that date".
The 25-year-old defendant was remanded on bail to a West Auckland address, ordered to surrender his passport and told not to apply for any travel documents.
The victim of the alleged hit and run was believed to have been crossing Great North Rd between the Mobil service station and Larch St when the Suzuki - driving in the right-hand, east bound lane - struck her. A member of the public contacted the investigation team leading to the identification of the woman, who was eventually interviewed.
She suffered some injuries from the collision but they were not life threatening, Detective Sergeant Kevin Blackman said.
It is believed a man, who was possibly driving a van, had stopped and offered to help the young woman as she lay on the side of the road after the defendant had allegedly driven off, according to police.
