In New Zealand as in most countries, the housing market is driven by two main variables: income and price. In a stable market, people purchase a home they can afford based on their income rather than the condition of the available inventory.
Like other needs, the requirement for housing is best met when people limit their choices to what is affordable instead of what is most desirable. This allows people to 'vote with their feet' if they perceive the cost of housing in a given location exceeds their income, is more than they are comfortable paying, or both.
The release of the unitary plan for Auckland has prompted much discussion. What we must bear in mind is something that sounds like a cruel elitist statement but boils down to pure economics: not everyone is meant to own their own home.
According to Maslow's hierarchy of needs, physical needs (safety and security) are basic, and housing is central to these. As long as safe, appealing and affordable housing is available to all who can afford it, people should be indifferent as to whether they own or rent their home. In most cases, renting is a much more affordable option (according to the 2012 Housing Europe Review, only 40 per cent of people in Germany own their home).
The drive for ownership might make good sense in a fairness and equity argument, but is often bad economic policy waiting to happen, and can be socially disastrous.
