New Zealand's water infrastructure system is leaking at a far higher rate than global leaders.
Otago University research shows 21% of piped water is being lost.
In comparison, the Netherlands loses 5% and Germany 6%.
The leaks are also wasting around $122 million each year.
Professor of Public Health Nick Wilson told Ryan Bridge that New Zealand has a network of very aging pipes that aren’t being fixed in the same way they do in Europe.
He says that leaking and breaking pipes are actually a concern from a public health perspective, as defects can increase the risk of disease outbreaks.
