The cost of disposing of rubbish is too high for many Northlanders according to Te Tai Tokerau MP Kelvin Davis, although that was just one factor.
Mr Davis, who spent part of last week knee-deep in illegally dumped rubbish, also pointed to excessive consumerism, sheer laziness and ubiquitous alcohol bottles as playing a part in the region's rubbish problem, which spanned native bush, beaches and even urban areas.
On Tuesday Mr Davis and a handful of volunteers were in the bush at the Waikare Gorge, near Karetu, cleaning up yet another illegal dumping site that he had happened upon a few days earlier while walking.
They removed two ute loads and one trailer load of rubbish, but he estimated that was only half the job. They planned to return to finish it.
"It was certainly a mess, and a horrible job," Mr Davis said.
