A 38-year-old man has been arrested after a woman was found bound and gagged on the side of a road in Dome Valley.
The man has been charged with kidnapping and appeared in the North Shore District Court today.
He has been granted interim name suppression and is due to reappear next week.
Police said in a statement they were not ruling out the possibility of further arrests "as the inquiry unfolds".
The victim remains in Auckland City Hospital in a serious but stable condition.
