Site-Led pest plants

Updated 14 November 2017 3:14pm

 

These plants are so widespread throughout our region that boundary control by landowners is really the only option.

If your neighbour has any of these pest plants try talking to them first about controlling the offending plant or working with them to try and get rid of it before asking us to get involved.

Your neigbours may not realise that it is a pest plant or that it is a problem to you.

There are two types of pest plants in this category:

  • BOUNDARY CONTROL - The main objective of boundary control is an attempt to prevent the spread of the pest plant onto properties that are clear of it.
  • HUMAN HEALTH - the main objective of the human health category is to minimise the risk to a person's health potentially caused by the specified plant.

When an adjoining landowner lodges a complaint with us, landowners are required to clear the pest plant back to the specified distance from their boundary.

Note: plants marked with an * are subject to Total Control within the Hutt City territorial authority boundary only.
