Police are investigating a potential abduction in Christchurch on Saturday night when a screaming and struggling woman was bundled into a car that drove off at speed.
The woman has not been heard from since and police admit they have "limited information to go on".
They want to hear from the two people involved in the incident around the Portsmouth St area in Aranui about midnight on Saturday to confirm that the woman is safe.
"We don't know what has happened there, whether it was a domestic incident or what," a police spokesman said today.
"We've got limited information to go on and want to know if anyone has heard anything and whether the woman is safe."
Witnesses have described the car as a black, two-door GT4 Toyota Celica, with a registration plate possibly starting with 'XS'.
The male driver is described as being Caucasian, aged around 20, about 180cms, with a ginger goatee and wearing a black hoodie.
Police urge anyone with information to contact them on 03 363 7400 or anonymously through Crimestoppers on 0800 555 111.
