Here is the basic infrastructure equation - and it comes from the Infrastructure Commission.

• “We spend a lot on infrastructure, but we don’t always get good value. New Zealand invested around 5.8% of gross domestic product (GDP) annually on infrastructure over the past 20 years, making us one of the top spending countries in the Organisation for Economic Co-operation and Development (OECD).”
• “Yet we rank towards the bottom for efficiency, or ‘bang for buck’.
• “In 2022, we spent almost $5000 for every person in the country (in 2025 dollars).”
• “We have 1175 land-use zones across 67 territorial authorities. Japan – which has more than 20 times the population of New Zealand – has 13.”
• “New Zealand must get better at asset management. At present, asset management maturity varies between sectors, and tends to be lowest for central government social infrastructure providers like health, justice and education. Contributing factors include a lack of understanding and awareness of the importance of asset management, inadequate information on assets, a lack of transparency and accountability, and insufficient enforcement of best practices.”
