General description

Evergreen resinous trees usually < 45 m tall. Bark is rough and often thick and fissured. Leaves are green, needle-like and produced in clusters. Cones contain many seeds.

What you need to know

Although pines are not legally declared pest plants (except for Pinus contorta), they may still be invasive in some situations. Consider lower-risk alternatives for your garden, such as native plants.


Open areas, coastal areas, shrubland, plantations.


Seeds dispersed by wind. Human-mediated dispersal through deliberate plantings.

Impact on environment

Outcompetes and displaces native vegetation. Some are allelopathic and can alter habitats.


Site Management

Follow up treated areas 3 times per year. Encourage natural regeneration of native plants or replant treated areas where possible after 2-3 treatments to establish dense ground cover and minimise reinvasion.

Recommended approaches

Physical control

Method: Dig or pull out seedlings. Cut stump close to the ground below lowest branches. Ringbark below lowest branches making sure the cambium layer is completely cut through if safe to do so.

Plant parts requiring disposal: Cones.

Disposal options: Remove to greenwaste or landfill if practical. 


Biocontrol is currently not available for this species.

Community agrichemical control recommendations

Certified Handler/Experienced agrichemical user: Foliar spray in summer with 100ml glyphosate green per 10L of water and 20ml penetrant.

Drill and inject trees with 750ml glyphosate green and 10ml penetrant per 1L of water if safe to do so. Drill 18mm holes (tangentially angled downwards) in a spiral up the trunk. For 50mm stems drill one hole. For 100mm stems drill two holes. For larger stems drill holes 150mm apart.

Safety notes

Large trees must not be ringbarked or drilled that are closer than 1.5 times the height of the tree from paths, walkways and property.

Trees over 4 metres in height should be removed by a qualified arborist.

Caution: When using any herbicide or pesticide please read the label thoroughly to ensure that all instructions and safety requirements are followed.

Pine branch tip with mature and immature cones.
Pines that have been introduced into NZ have successfully produced viable seed that has created wilding pines. Well suited to NZ conditions, wilding pines are quick to grow and can dominate an area.
Pine sapling growing on mountain side.
An evergreen pine that can grow up to 45m tall and produce large amounts of seed in cones. Seeds have wings and are distributed by wind and gravity.
Close up of pine tree trunk.
Pines are a favourite habitat of possums and pine forests can become possum breeding grounds. Felling pines will prevent their re-growth and timber is suitable for firewood.
