I want to be the Finance Minister in two years time. I'm acutely aware that money is going to be tight. Every dollar needs to be spent wisely.
I'm not convinced that under-investment in public infrastructure is the cause of New Zealand's economic under-performance at the moment. Therefore, the economic benefits for spending on infrastructure are going to have to stack up well. Our infrastructure spending has been noticeably stop-start over the past 30 years.
New Zealand was broke when National's Sir Robert Muldoon left office in the 80s. Later governments had to pay for critical services like teachers, nurses and police while restoring the nation's crippled books. They cut back on capital expenditure. As a result we went through about 15 years of under-investment. There was little choice about scaling back infrastructure investment then, but with hindsight it's clear the tap should have been turned back on earlier.
Having not spent enough for so long, further delays were caused because it takes a while to plan infrastructure projects and that was not started early enough.
So by the time the Government started spending on infrastructure again we were into the 2000s, and a two-decade long investment deficit needed to be made up. The tap was turned back on very hard, and we have very good basic infrastructure now to show for it.
