Residents in Manawatū-Whanganui are being asked to check any old or recent smouldering rubbish and land clearance fires to ensure they are fully out.
Fire and Emergency New Zealand (Fenz) District Manager Nigel Dravitzki said there was extreme fire risk for some parts of the district over the coming days and all precautionary measures needed to be taken to prevent wildfires.
"This means checking the sites of old fires, making sure they are fully extinguished, and making sure there is no chance of them reigniting."
Wildfires caused by old open-air fires which hadn't been extinguished properly put a strain on firefighting resources and were preventable, Dravitzki said.
"Please reduce the risk by checking your old fires."
