pressing dimensions of the right in the Aotearoa context, for example, housing habitability and affordability. They also prioritised data sources that were most technically reliable and that would continue to be produced in the future. That’s important because we want to be able to track progress in future years. This exercise used existing, publicly available data; it did not collect new data. In recent years there has been progress made in measuring different aspects of the right to a decent home: such as estimates of homelessness, additional data on affordability and housing habitability, and the development of government dashboards on housing. MAIHI Ka Ora also establishes an action to develop a Māori-led Housing Data framework which will identify key data gaps around the adequacy of Māori housing.49 Despite this progress, the existing data is insufficient to capture all dimensions of the right to a decent home, particularly around cultural adequacy. The Commission is also planning a project on an indigenous rights monitoring framework to reflect tangata whenua priorities in the selection of indicators, analyses, and reporting. For example, this could include developing indicators that measure Aotearoa’s progress in relation to the right to a decent home, Te Tiriti o Waitangi, and the United Nations Declaration on the Rights of Indigenous Peoples. The Motu study identified seven dimensions of the right to a decent home. It then identified indicators to track progressive realisation for each of these dimensions. Those indicators suggest there has not been progressive realisation in relation to the affordability dimension of the right to a decent home. On the contrary, things have got worse since the 1980s, suggesting there is a violation of the right to a decent home. We have used the Motu study to inform a selection of indicators to measure the progressive realisation of the right to a decent home in Aotearoa. Like the Guidelines and the Motu report, we explore seven dimensions of the right to a decent home: • Affordability • Habitability • Accessibility • Security of tenure • Location • Access to core services • Cultural adequacy. The Measuring Progress indicators for each dimension help us to measure the progressive realisation of the right to a decent home grounded on Te Tiriti o Waitangi. Measuring Progress will show at a glance whether key dimensions of the right to a decent home are being achieved or not. Our website will also provide a deeper breakdown of the indicators and what they show about housing in Aotearoa. Alongside this report we are releasing the results for one dimension of the right to a decent home: affordability. Affordability Affordability is one dimension of the right to a decent home based on Te Tiriti o Waitangi. Housing costs, including for energy, should not compromise the ability of people to afford other reasonable needs. Tenants should be protected by appropriate means against unreasonable rent levels and increases.50 Housing affordability is about people’s capacity to pay housing costs. These can include entry costs (e.g. building costs, home deposits, or bond to enter a tenancy) and ongoing expenses (e.g. mortgage or rental payments, insurance, rates, repairs and 27
