Judge Thompson said it was to Hansen's credit that he did remedial action when approached about the issue.

"The council has an obligation under the RMA to enforce our district plan rules and RMA legislation, and we will investigate any offending and place offenders before the courts.

"We remind all landowners that resource consents are required for vegetation clearance in many areas, as it can have a significant impact on land stability and water quality.
"The council does monitor and enforce consents."
