Registration of non-spray areas

Tasman District Council’s roading maintenance contractor is responsible for vegetation control within the road reserve. This includes the use of knock-down, residual and brushweed herbicides to remove vegetation growing in the roadway and around street furniture. The active herbicides authorised under Council’s resource consent are norflurazon, oryzalin, simazine, terbuthylazine, glyphosate, metsulfuron, haloxyfop, triclopyr and picloram/triclopyr. Methods for treatment are foliar and basal spraying.

Residents can request that their rural property frontage not be chemically sprayed and instead undertake the vegetation control themselves. On approval Council will mark the 'no spray' area with red marker pegs.

Rural residents who choose the 'no spray' option must control the vegetation growth along their property frontage to ensure road users are not impeded and all roadside signs and markers are clearly visible. Vegetation height should not exceed 300mm. Any stormwater drainage ditches need to be kept clear. At intersections vegetation must be kept well clear to ensure good sight lines for traffic using the intersection.

If you wish to apply for your property to be added to the 'no spray' list, please contact Nikki Shepherd, Technical Officer Transportation, Tasman District Council – phone 03 543 7234 or email

Roadside spraying on state highways

Contractors employed by Waka Kotahi (NZ Transport Agency) undertake an ongoing vegetation control programme to ensure that roadside vegetation does not affect the safety or operation of the region’s state highway network.

This programme includes the spraying of chemical herbicides including the following active ingredients: glyphosate, metsulfuron, terbuthylazine and triclopyr. These sprays are applied from a vehicle via a mechanical arm or boom, or via a handheld device.

Anyone wishing to register their property as a ‘no-spray’ zone, which requires a commitment to maintain a property’s highways frontage to specifications provided by Waka Kotahi, may do so by contacting Nicole White on 03 548 1100,, or at WSP, Private Bag 36, Nelson 7010.
