Police have set up a toll free 0800 number as they continue to seek information from the public following the vicious assault of a woman in Riverhead early on Sunday morning.
Detective Senior Sergeant Kim Libby, of Waitemata Police, said the response from the public so far had been outstanding, with more than 50 calls received by the inquiry team.
Messages and private messages have also been sent to the Waitemata Police Facebook page following the incident, in which an injured 23-year-old woman woke in a quarry partially naked with a man standing over her with a bat.
Inquiries are continuing and a toll-free number - 0800 605 506 - has been set up for people to continue calling with information.
"We're still after any information about the car seen driving into and leaving the quarry, or any information about the man seen at the petrol station in the footage we released on Monday.
