He said it was expected to have the examination and the body removed today.
Earlier, fire service shift manager Megan Ruru said two fire crews were called to the Te Rahu Rd house at Poroporo shortly after midnight.
A house was "well ablaze"when they arrived.
Ms Ruru said they were told there was a possibility someone was still inside the burning house.
"Shortly after they found one occupant, thought to be a male, in the lounge," she said.
The owner of the farm where the fire took place said he was "too upset"at the moment to talk about it.
"The family [of the man] hasn't actually been contacted," he said.
