Broadcaster Susan Wood is recovering from a head injury suffered during a fall at her home.
A statement issued by her sons, Alex and Matt, said the accident happened on 10 January and the Q+A host was now in rehabilitation.
"In response to interest shown by the news media, we can confirm that our mother, Susan Wood, is recovering after an accident, and is now in rehabilitation after being discharged from Auckland Hospital," they said.
"We thank all involved in her care at Auckland Hospital for their dedication, their expertise and their humanity.
"Their treatment of our mother was outstanding. We also appreciate the concern and goodwill shown by others.
"We do not plan at this stage to make further comment and ask for privacy at this time."
A TVNZ spokesperson said the broadcaster was saddened to hear of Wood's accident.
"Susan is a much respected and admired member of our newsroom. She will be in her colleagues' and our viewers' thoughts as she recuperates," the spokesperson said.
"We will be supporting Susan in her recovery, and we ask that her family's request for privacy during this challenging time is respected."
Lucy Knight, who suffered a serious head injury when she went to the aid of a woman being mugged in Auckland last year, took to twitter to offer support to Wood.
"Sorry to hear about Susan Wood's accident. I hope she does get some privacy to recover in. Head injuries can take some time."
