Illegal dumping on and alongside Bay of Plenty state highways is taking time and money away from essential state highway maintenance, Waka Kotahi NZ Transport Agency says.
Waka Kotahi is responsible for rubbish collection on and alongside state highways.
Bay of Plenty system manager Rob Campbell said earlier this month contractors came across a large pile of rubbish, including furniture, clothing and a dead pig at a single site on State Highway 30.
"The cost for clean-up and disposal for a single site like this can sometimes stretch into the thousands of dollars; considerably more than it would cost someone to take it directly to their local landfill," he said.
"Unfortunately, this isn't uncommon. In the past three months we have had similar clean-up sites elsewhere on SH30, on SH2, SH5, SH29, SH33 and SH38."
