Fire crews are fighting a fire that has "totally destroyed" a house in the Wellington suburb of Wadestown.
The blaze on Barnard St has spread to nearby vegetation but no-one was thought to have been in the house or vicinity of the fire, which started after 3pm, Fire Service communications shift manager Jan Wills said.
"The house is just about totally destroyed."
Two neighbouring houses were evacuated for safety and Barnard St and surrounding roads had been closed by police.
Twelve fire engines and Wellington Free Ambulance are on the scene.
Services on the Johnsonville Line were replaced buses between Wellington and Ngaio due to the incident and travellers were advised to expect delays.
All rail services departing after 4.20pm would be replaced by buses until further notice.
Police central communications shift commander Inspector Ken Climo said "plenty" of police were dispatched to the large fire, the smoke from which could be seen from across Wellington Harbour.
There were no reported injuries.
"It's fully engulfed," Climo said. "And the wind is whirling the smoke around, which is covering a large area."
Care was also advised for State Highway 1 traffic near the Interislander ferry terminal as many cars slowed down to "rubberneck" the blaze.
