The Labour-led government risks electoral defeat in 2020 unless it makes demonstrable progress on affordable housing this year, says the outspoken author of an annual survey of global housing affordability.
Hugh Pavletich, the Christchurch-based co-author of the Demographia International Housing Affordability Survey, says in his introduction that the results of the 2019 survey "will come as a shock" to New Zealand's Labour-led government.
Billed as "the world's largest known collection of housing affordability data at the housing market level", the 2019 survey is the 15th in the series. It concentrates on what it calls 'middle-income housing affordability' rather than subsidised housing for low-income households and measures median house prices by median annual gross pre-tax household income.
On that basis, it finds Hong Kong has the world's most unaffordable housing, with a ratio of median house price to median household income of 20.9 times. New Zealand is ranked second at nine times in 'major housing markets', although this drops to 6.5 times when measured across all housing markets in New Zealand. The major markets unaffordability in New Zealand is driven particularly by Auckland and Tauranga, ranked the eighth and ninth least affordable cities, with ratios of 9.1 and 9.0 respectively. The survey covers 309 cities in the English-speaking world plus Singapore and Hong Kong,
Sydney at 11.7 times and Melbourne at 9.7 times rank as the third and fourth least affordable, while Hong Kong and Vancouver top the list. Palmerston North ranks as New Zealand's most affordable city, with a median price to household income ratio of 5.0.
