Her asthma had been "exacerbated" by the house, Ms Martin said.
Housing New Zealand spokeswoman Bryony Hilless said ceiling insulation and a hot-water cylinder wrap were installed at the house in late 2010.
"Our records also confirm we visited the property on a regular basis and no specific maintenance issues or requests were noted as requiring follow-up.
"We have also found no specific references to the property impacting on the health of Ms Nadin."
While there was a woodfire in the house, under the Residential Tenancies Act there was no obligation for landlords to install curtains.
Ms Nadin and her partner, Dennam Dette, 70, stayed at the Housing New Zealand property because they liked the area and thought the issues would eventually be sorted.
Since moving to a private rental in Otangarei, which costs about $100 extra a week, Ms Nadin had only been into hospital twice.
"This is her life saver," Mr Dette said.
