Appliances from the Whanganui Fire Brigade were called to the scene of a fire in Bulls.
Two buildings used for manufacturing honey were described as "fully involved with fire" on Edward St, just off State Highway 3 north of the Rangitikei town.
The Central Fire Communications Centre started receiving calls about the fire at 4pm on Saturday and units from Bulls and Marton were deployed.
Central Fire Communications Centre shift manager Mike Wanoa said the blaze took some time to get under control.
"We had a problem with access to water at the time because there was a problem with the water main in the area, so we had to respond with tankers from Marton initially," Wanoa said.
