Affordability in New Zealand

This website is produced by MRCagney as a public education tool illustrating the multifactorial nature of affordability and how big a role geography plays in it. Our analysis is inspired in part by the article "Housing and Transport Expenditure: Socio-spatial Indicators of Affordability in Auckland" by K. Mattingly and J. Morrissey [MaMo2014] and is updated at the end of every calendar quarter. This website is also open source, and its data and source code can be found on Gitlab .

Data and Methodology

Frequently Asked Questions

Why are there so many n/a values on the maps?

That's mostly because we are using only the last six months of rental bond data from MBIE, and many rental areas haven't had new bonds lodged then. We could remedy that by using older data for those areas, say from the last 1–2 years, but that's probably more misleading than informative.

So what is affordable, that is, what fraction of my net income should I be spending on rent and commute costs?

That depends on your financial targets. For example, if you want to live frugally like Mr. Money Mustache, then you want to save at least 65% of your net income, leaving at most 35% for expenses. Some of that needs to go to food, clothing, healthcare, etc., leaving roughly 20% of net income for rent and commutes.

Why not include other costs in the app, such as food, power, and Internet?

We want to emphasize the spatial nature of affordability and balance accuracy with simplicity, informing but not overwhelming the user. So we include the dominant and most spatially variable costs and exclude the rest, such as food, power, and internet.
