Whanganui District Council's property and services committee will next week consider a proposal to alter the name of a landmark building.
After Land Information New Zealand announced that "Wanganui" would officially become "Whanganui" in 2015, the Royal Wanganui Opera House was the only municipal building to retain the former spelling of the district's name.
Councillor Josh Chandulal-Mackay said he initiated the proposal to change the Opera House's name after investigating the anomaly.
"Initially, there were concerns that because the Opera House uses 'Royal' in its name, that we would have to gain the express permission of the Queen to alter the name," he said.
"The Ministry of Arts Culture and Heritage has since confirmed that an alteration of this nature does not require approval from the governor-general or the Queen of New Zealand."
