An engineer's report has eased fears the Hundertwasser toilets in the Northland town of Kawakawa, are at risk of collapse.
The report for Far North District Council says while cracks which have appeared are unsightly, there is no risk to the building's structure.
Maintenance staff had noticed a growing number of cracks and movement in the toilet block, which is one of the town's biggest attractions.
The council describes the toilets as a functioning artwork, designed and supervised during construction by an internationally-known artist, the late Friedensreich Hundertwasser of Austria.
The toilets remain open and the council will monitor the building while it considers longer-term options to stabilise it.
