Fire crews battled a blaze in the roof of Dunedin's St Paul's Cathedral on Tuesday morning.
Emergency services were called to the iconic building in the city centre at 3:30am.
A Fire and Emergency New Zealand spokesperson told Newshub the blaze is now contained but seven crews and a command unit remain at the scene. The blaze was located at the back of the church.
Road closures are in place around the Octagon, police said in a statement.
"Closures are in place on Stuart St, from Moray Pl at the top end of the Octagon to the centre of the Octagon, and on Moray Pl from Filleul St to Stuart St.
"Motorists should avoid the area or expect delays."
A fire investigator will head to the scene later on Tuesday.
