Last year's budget did not allocate enough money to address the infrastructure deficit, which is estimated to be $75 billion. New Zealand must address this to meaningfully improve living standards. Central and regional authority funding will always be vitally important to improving infrastructure, but appropriate private sector finance has a key role to play in advancing these objectives and addressing New Zealand's infrastructure requirements.
