​​​Broom is a widespread and abundant weed throughout much of Southland.

What is it?

Broom is a woody deciduous shrub, easily recognisable in spring by its bright yellow flowers.

Why is it a problem?

Broom can dominate sites reducing the amount of grazing available to stock and inhibiting growth of desirable species. In urban areas, broom can harbour pest animals such as rats and possums, and pose a fire hazard.

How to control it

Broom can be controlled via the following methods:

​Control method
​Mechanical and manual control
Chainsaws, brush cutters, loppers and handsaws. Mulching, root raking with a digger.​
​Herbicide control
​Biological control / biocontrol
Instects such as the broom gall mite, broom psyllid and broom twig miner all reduce the vigor of broom. Read more on our biocontrol page.

For details on control methods, see our factsheets - broom and gorse in rural areas and broom and gorse in urban areas.

Pest Classification

Broom is a Suppression Plant throughout the Southland region. It is too well established to eradicate, so our aim is to prevent it spreading onto neighbouring properties.


There are separate rules for broom in urban and rural parts of the region.

  • For urban areas, broom must be destroyed completely.
  • In rural areas, broom must be destroyed within 10 metres of a property boundary and within 10 metres of a watercourse. Existing hedges are allowed provided they are regularly trimmed.

For a full explanation of the rules for broom in the Regional Pest Management Strategy.


We monitor urban areas for broom each year. For rural areas, we respond to complaints received about broom within 10 metres of neighbouring properties. Priority is given to complaints received from land occupiers who are directly and adversely affected by the presence of gorse and broom at a shared boundary.
