BRANZ surveyed the condition of a large sample of New Zealand houses approximately every 5 years from 1994 to 2015. 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 included an on-site physical house assessment, a telephone interview with the occupant and an appliance use questionnaire.
This BRANZ Research Now series focuses on findings around energy efficiency, maintenance and subfloor condition.
