"We understand the fireplace can't be used any more because it is an open fireplace but it is not the landlord's responsibility to buy heaters."
The mother said they were counting down the days until winter was over.
"My family is warm and fed and as long as we're all together it's all good. But this is what we have to do. This winter seems to have definitely been the worst, we have the oven on all night, everything is closed, the curtains shut and a [lounge] chair blocking the fireplace but when you wake up in the morning the top of the blankets are wet. It's like it's warmer outside than it is inside.
"There is no insulation so if the kids need to go to the toilet we have to wrap them up in their jackets and slippers - it's only five steps away down the hall but it's just too cold. I don't think we're unique, I think there are a lot of families in Rotorua in the same predicament as we are," she said.
Work and Income made more than 640 hardship payments in the Rotorua region for electricity and gas in the year ended March.
Ministry of Social Development figures showed the ministry paid out $282,137 in the Rotorua region from March 2014 to March 2015, down from $402,000 last year.
"Hardship assistance is available where there is an immediate and essential need and no other way to meet the cost," a ministry spokesman said.
"There is also a range of other assistance available depending on a person's circumstances.
"People who face extra heating, gas or electricity costs because of a disability may qualify for a Disability Allowance to help with these costs." Temporary additional support could also be available.
