Protect Mauao - Stop the Spread of myrtle rust
Toa o Te Taiao highlights the growing threat of myrtle rust and the impact it has on our native taonga species. This mural encourages the community to stay vigilant and take an active role in protecting the health and resilience of our taiao for future generations.
What is myrtle rust...
Myrtle rust is a serious plant disease that threatens taonga species like pōhutukawa, mānuka, and rātā – including those found on Mauao. It spreads easily on the wind and has no known cure, but we can all help slow its impact by staying vigilant and reporting any signs.
What does it look like?
Symptoms of myrtle rust include:
- Bright yellow powdery eruptions appearing on the underside of the leaf (young infection)
- Bright yellow powdery eruptions on both sides of the leaf (mature infection)
- Grey, 'fuzzy' spore growth on undersides of leaves
- Some leaves may become buckled or twisted and die off.
What should I do if I find myrtle rust?
If you think you see the symptoms of myrtle rust:
- take a clear in-focus photograph of the whole plant, the affected leaf, and a close-up of the spores
- submit the photograph to Myrtle Rust Reporter - iNaturalist website
Make sure you label your finds as myrtle rust, noting what host plant it has been found on. Capturing this information through iNaturalist means it will be available in future to analyse the rate of spread and observed impacts.
If you see myrtle rust on public land you can report your myrtle rust sighting to:
- your local council
- the Department of Conservation (DOC) if sighted on public conservation land.
For other myrtle rust queries, contact the Ministry for Primary Industries (MPI). Including reports of:
- New host species
- Movements of infected plants

Remember, don't try to collect samples as this may increase the spread of the disease.
