Rethinking cost-benefit through a Te Ao Māori lens

A Te Ao Māori approach asks us to slow down and lift our gaze. It's grounded in an intergenerational worldview, where decisions are made with an awareness of whakapapa - the unbroken human connection between past, present and future. From this perspective, infrastructure isn't just a physical asset or a line on a balance sheet. It's part of a living system that sustains people, whenua and wai long after the current generation has moved on. 

Encouragingly, we’re beginning to see planning frameworks in Aotearoa move closer to this way of thinking. The shift toward 30‑year spatial planning horizons is a meaningful step in the right direction. While 30 years is still relatively short when viewed through a Māori lens, it represents a move toward more strategic, place‑based decision‑making. It lets us think more carefully about how regions grow, how pressures accumulate over time, and how today’s choices shape tomorrow’s options. 

In Māori contexts, planning horizons are often much longer. It's not unusual to think in terms of 50 or 100 years, and, in some cases, even further. One organisation, for example, worked with us to explore what a 200‑year strategy might look like. That wasn't about predicting the future in detail, but setting a direction of travel - because, when you plan over centuries rather than decades, it becomes much easier to distinguish between what is truly important and what is merely urgent. 

This kind of long‑term thinking is shaped by many Te Ao Māori principles. Kaitiakitanga places responsibility for the care of the environment at the centre of decision‑making, recognising that environmental health underpins all other forms of wellbeing. Ukaipōtanga emphasises connection to place, ensuring infrastructure strengthens communities’ relationship with their whenua rather than eroding it. Whakatipuranga keeps future generations firmly in view, asking decision‑makers to consider cumulative benefit, not just immediate gain. 

Other principles also play a critical role. Wairuatanga acknowledges the deeper relationships between people, place and purpose. Mātauranga values indigenous knowledge alongside technical and economic expertise. And Mana ōrite has Māori perspectives sitting alongside conventional frameworks, not beneath them.  

This worldview challenges conventional cost–benefit analysis, especially the way it discounts the future. In many models, benefits delivered decades from now are treated as less valuable than those realised today. A Māori perspective doesn't accept that framing. Each year that infrastructure functions well - safely, sustainably, and in balance with its environment - has value in its own right, especially when that benefit accrues to children and grandchildren. 

This isn't about replacing existing tools, but about improving them. When Māori measures of success are developed alongside technical and economic analysis, decision‑making becomes more robust. Investments are better aligned with place, more resilient to future shocks, and more likely to deliver enduring value. 

Ultimately, a Te Ao Māori lens reminds us that infrastructure isn't just for now. It's a legacy. And the responsibility to get it right extends well beyond the present generation.
