Two fires last night - one deemed suspicious - are being looked at by Christchurch fire safety officers.
The first occurred in Ashburton at 4.50am and fire safety officers were investigating to determine the cause, Southern Fire Communications spokeswoman Lyn Crosson said.
"No persons [were] injured, nothing like that, it was just a house fire, but going well when we arrived.
The house was occupied, however the residents got out, Ms Crosson said.
Three fire engines attended the blaze, she said.
