A young woman has been seriously injured after a car collided with a tree near Waipukurau just after midnight on Thursday.
Emergency services were called to a single-vehicle crash at the intersection of Bush Rd and Porangahau Rd in Wallingford about 12.36am.
A Fire and Emergency New Zealand (FENZ) spokeswoman said one person in the crash was extricated from the vehicle and stabilised before being transported to Hawke's Bay Hospital via air ambulance.
A Hawke's Bay District Health Board spokeswoman said two people were taken to Hawke's Bay Hospital following the crash.
A woman in her late-teens remained in a serious but stable condition on Friday morning, while a man in his 20s had since been discharged.
Hawke's Bay Rescue Helicopter Trust general manager Ian Wilmot said the rescue helicopter was called to the crash about 1.30am.
