BRANZ has surveyed the condition of a large sample of New Zealand houses approximately every 5 years since 1994. The 2015 sample of 560 houses was designed to be broadly representative of the national housing stock and included both owner-occupied and rental houses. The survey comprised an on-site physical house assessment, a telephone interview with the occupant and an appliance use questionnaire completed by the occupant.
The three Research Nows focus on findings around energy efficiency, maintenance and subfloors:
1. Energy efficiency in the New Zealand housing stock
2. Maintenance and deferred maintenance in New Zealand houses
3. The state of our subfloors
