Christchurch authorities are being slammed for letting a heritage-listing building go abandoned.
The abandoned villa, featured in Peter Jackson's film Heavenly Creatures, went up in flames shortly after 5.20am on Tuesday.
Heritage campaigner Dr Anna Crighton said the council and Heritage New Zealand need to take a harder line on owners who let heritage buildings deteriorate.
"They're just toothless tigers really you can have all the words you like in a district plan but you have to put it into action and really clamp down on these people.
"It's really demolition through neglect."
