New Zealand faces a $49 billion water infrastructure bill but has abandoned the census that would guide where and how to invest. The government is making massive spending decisions without the data that used to underpin planning.
The consequences of scrapping the census are becoming clear, according to RNZ. Without accurate population data, how do you plan infrastructure for a country you're not properly counting?
Mate, this is governing with a blindfold on. New Zealand needs to spend tens of billions on water infrastructure, but we don't actually know where people are living, how fast communities are growing, or what the demographic makeup is. Good luck with that.
The census has been the backbone of infrastructure planning in New Zealand for more than a century. It told planners where to build schools, hospitals, roads, and water systems. It provided demographic data essential for everything from electoral boundaries to social service allocation.
Now it's gone. The government decided the census was too expensive and too difficult to administer effectively. Instead, it's relying on administrative data—information already collected by government agencies—to fill the gap.
But administrative data doesn't capture what the census did. It misses people not interacting with government services. It lacks the granular geographic detail needed for local planning. And it doesn't provide the comprehensive demographic picture that made the census valuable.
The $49 billion water infrastructure challenge illustrates the problem. New Zealand's water systems are aging and inadequate. The government has acknowledged that massive investment is needed. But without census data, how do you prioritize where to invest?
You could invest based on current problems—areas with failing infrastructure get priority. But that's reactive, not strategic. It doesn't account for population growth or demographic change. You might spend billions building infrastructure in communities that are shrinking while ignoring fast-growing areas.
