Hawke's Bay Opera House's Theatre Building has been closed following engineering advice that it is earthquake prone.
Several million dollars was spent upgrading the 99-year-old building, owned by Hastings District Council, between 2004 and 2007.
"A 2013 report on the earthquake strength of the Opera House Theatre provided assurances over building safety but advised that further work be done," Hastings Mayor Lawrence Yule said today.
"Council has taken the prudent approach of commissioning further investigation. This work involved invasive testing of the structure and foundations, and the indicative verbal advice that we have now received is that the theatre is earthquake prone."
The verbal advice of the lower earthquake rating has been received from engineers in advance of the finalised testing and reports which are due on March 21.
