As the New Zealand and Australian Governments hand down Budgets within days of each other, the striking feature is the contrasting fortunes of the two economies and the impact on Budget bottom lines. New Zealand's economy is booming, Australia's growth is sub-par.
New Zealand's growth is supported by four factors. The massive post-earthquake Canterbury rebuilding is on the rise, with spending estimated to be around 20 per cent of New Zealand's GDP over a decade. Low interest rates support a pick-up in the housing market and household consumption. Strong demand for dairy products from China is driving an agricultural boom that is lifting local incomes and investment. And strong economic conditions are attracting migrants, which is also supporting demand. We expect to outperform almost all other OECD economies this year.
By contrast, after a mining boom Australia's transition to rebalancing growth towards the non-mining sectors is not without problems. With iron-ore and coal prices also past their peaks, tax-revenue growth has slowed and is unlikely to be as strong as it was during the mining boom.
These divergent trends explain much in the Budget bottom lines. Australia has a budget deficit of 3.1 per cent of GDP, with its new Government planning to make cuts to head back to surplus over the next five years. New Zealand is almost in surplus, after six years of deficits, with projections suggesting surpluses from next financial year onwards.
There are lessons for policy makers on both sides of the Tasman. New Zealand should make the most of the current good times to lock in government savings and invest in productivity enhancing reform. Australia did not, and faces tough measures at a less-convenient time.
