The police say they don't believe there's a link between the disappearance of an Alexandra woman and the airing of a TV show about her and her husband's campaign against a wrongful conviction.
Denise Potter, who's 53, went missing from her daughter's Dunedin home on Monday.
A documentary on TVNZ last week showed how she and her husband, Steve Potter, have campaigned against the conviction of their daughter's former boyfriend, Shane Gribb, for dangerous driving causing injury.
Mr Gribb was exonerated after a retrial.
Mr Potter said he doesn't think his wife has wandered far, because she was tired and not wearing shoes.
The police said they had not ruled out foul play, but so far there was nothing to suggest that.
