A fire has "totalled" a commercial building in the Hamilton suburb of Frankton.
Fire Service spokesman Steve Smith said about eight fire trucks were at the fire, which started about 9.40pm in the two-storey building on Wickham Street.
Hamilton Senior Station Officer Daryl Trim said the fire "pretty much totalled" the building, which housed waste disposal company Allens United Waikato Ltd.
No one was trapped or injured in the blaze.
The fire was still being investigated, and it was not known if it was suspicious, Mr Trim said.
He believed there were vehicles in the building, as well as flammable equipment which had to be cooled so it would not explode.
Hamilton firefighters also attended a house fire this morning. No one was injured but it was being investigated to see if it was suspicious.
