Nelson City Council gives annual notice of its ongoing chemical control of pest vegetation, near and in Nelson streams and rivers (permitted or consented where applicable).

Chemical control rounds are programmed dependent on growth, weather, vegetation present and plant cycles at any time of the year. 

The following areas below will be treated with some or all of the listed chemicals:

  • All rural and urban rivers and streams – includes Arapiki, Brook, Hillwood, Jenkins, Maire, Maitai, Oldham, Orchard, Orphanage, Poormans, Saxton, York, associated named and unnamed tributaries and waterways within Nelson City Council managed boundaries. 
  • Glyphosate, Triclopyr triethylamine, Metsulfuron-methyl.
  • Applied with knapsack, low pressure hand lance or brush. 

Residents living adjacent to the above streams, rivers and waterways may register their properties as a “No-Spray” property. Applicants for No-Spray areas will be required to maintain their neighbouring boundaries to control all unwanted weeds/organisms in that area.

Application forms to register as a “No-Spray” property may be collected from the Customer Service Centre Civic House, Trafalgar Street, Nelson, or from the website. For more information on the ‘No Spray Register’ please contact Council on 03 546 0200.

The Nelson City Council’s policy is to use the least toxic chemical necessary to control unwanted weeds / organisms. All chemical applications are carried out by Growsafe certified staff and best practice as per NZS8409:2004 Management of Agrichemicals.
