River pollution patrol in New Zealand's north...
Northland’s Wairua River with a 750 sq km catchment is one of the major rivers flowing into the Kaipara Harbour — our largest estuary, a nursery area for snapper and other fish and an essential habitat for migratory waders. The Wairua drains what was once the magnificent Hikurangi Swamp. Sadly, this is now largely drained and converted to farmland.
The muddy brown waters of the Wairua show our mistreatment of rivers and our gross carelessness about their health and our own.
