Discretionary income in Tauranga has risen according to the PwC Competitive Cities report that has been released.

Infrastructure New Zealand chief executive Stephen Selwood says the report also underlines the urgent need for the Government to deliver affordable housing and efficient transport systems in our growing cities.

He says PwC compared the performance of 11 Australasian growth cities over the last decade and found that households in successfully growing Australian cities have enjoyed significant improvements in discretionary income, relative to New Zealand.

'Discretionary income is the money left over after tax and spending on housing, transport and other essentials. It provides an insight into the quality of life in each city,” says Stephen.

According to the report, discretionary incomes in Tauranga, Hamilton and Queenstown increased by around $60-$70 per week.

'Perth, Brisbane and Adelaide households each saw increases of between $300 and $400 per week over the ten years from 2008-2018,” says Stephen.

'New Zealand's top performing city, Wellington, saw median household discretionary income increase by $137 per week, or around one-third that of Perth.

'Even Christchurch, which experienced a devastating series of earthquakes in the assessed period, saw discretionary income increase by $124 a week.

'Auckland was the only city to experience both increasing costs and flat income growth. Sydney's equivalent growth in the cost of living was offset by rising real incomes. Weaker income growth in Tauranga, Queenstown, Hamilton and Melbourne, on the other hand, was ameliorated by smaller growth in the cost of living.

'The reason for New Zealand's weaker performance is not explained by Australia's higher economic and therefore income growth.

'It is in the cost of living that we have struggled.

'High urban land prices have increased the amount households and businesses must spend on accommodation and rent. In addition, increasing congestion combined with higher transport taxes and fares have pushed up travel costs, not only for households, but for the producers and sellers of goods and services thereby making our economy less competitive.

'New Zealand's failure to manage growth is seeing the standard of living fall further and further behind Australia's attractive second tier cities.

'The Government's well-being budget, urban growth agenda and plans for fundamental review of our planning laws and local government structure and funding have the potential to address systemic problems across New Zealand.

'Bi-partisan political support will be needed to enact major reform of our deficient planning, governance and funding system which is the root cause of the problems we are facing.

'Meanwhile, decisive action is now required to address immediate growth pressures.

'Increasing the supply of land is one critical response. Urban land must be made more affordable in sufficient quantities to attract investment and enable scale.

'The other critical element is servicing that land with infrastructure so that homes and businesses can be delivered. Plans to enable private financing of infrastructure for housing development need to be accelerated.

'A step change in the supply of serviced land is urgently needed. With the construction sector operating at close to capacity, productivity improvements are the only real option to deliver the infrastructure and homes New Zealand needs.

'Clarity of the project pipeline, policy certainty and development at scale are the three essential elements to lifting construction sector productivity and encouraging investment in capital, skills and expertise in New Zealand and from overseas.

'There really is no time to waste. New Zealand households are already paying $200 per week more than households in Perth to cover the inflated cost of housing. Without urgent action we risk another brain drain simply because our housing markets do not function.

'New Zealand can materially and significantly lift real incomes, reduce the need for Government transfers and enhance liveability by resolving the growth crisis. This is the Budget where things must start to happen,” says Stephen.
