Start where you are,

Be a guardian of wetlands and waterways.

You don’t need a science degree or a seat in parliament to save one of Aotearoa’s most endangered birds. The Australasian Bittern (Matuku-hūrepo) is a master of camouflage, but it cannot hide from the fact that 90% of its wetland homes have vanished.

When we lose wetlands, we lose more than just a bird; we lose the “kidneys of the land”. These soggy, often overlooked areas are our best defense against a changing climate and the key to clean, clear freshwater.

Instead of feeling overwhelmed by environmental loss, look at the water in your own community and ask yourself:

What do I want to see? (Clear water? The booming call of a Matuku?
What can I do right now to help?

The Superpower of Wetlands

Wetlands are nature’s multi-tool. By protecting and incorporating them into our landscapes, we gain:

Natural Filtration: Wetland plants act like giant sieves, trapping sediment and “cleaning” pollutants and nutrients from the water before they reach our rivers and oceans.
Flood Protection: During heavy rain, wetlands act like giant sponges, soaking up excess water and releasing it slowly, protecting our homes from downstream flooding.
Climate Resilience: Healthy wetlands are carbon “sinks,” locking away massive amounts of carbon that would otherwise contribute to global warming.

5-Minute Wins for our Wetlands

You can start protecting our Matuku-hūrepo and our water quality today with these quick actions:

Become a “Drain Guardian”: Check your local street drains. Ensure no litter, oil, or soapy car-wash water is entering them, as these often flow directly into the nearest waterway. More information on how to be a drain guardian can be found here.
Record a “Boom”: If you live near a wetland, learn how to listen for the low, foghorn-like “boom” of the male Bittern at dawn or dusk and join the Great Matuku-hūrepo Muster in Spring! Reporting what you see or hear on www.lovebittern.com . eBird or iNaturalist helps us to protect their remaining habitats.
Audit Your Cleaners: Spend five minutes checking the labels of your household cleaners. Switching to “septic-safe” or biodegradable products reduces the chemical load on our groundwater and wetlands.
Prep a Planting Plan: Research one native wetland plant, like Harakeke (Flax), Rāupo (bullrush), or Oioi (jointed-rush) –that you could add to a damp corner of your property or suggest for a local park. These plants provide essential nesting and foraging cover for the Bittern who don’t like to be under a canopy of trees!.
Check Your Boots: If you’ve been near water, take five minutes to “Check, Clean, Dry” your gear. This stops the spread of invasive weeds and pests that can choke a healthy wetland ecosystem.

Our Shared Responsibility

The Matuku-hūrepo is a “Nationally Threatened – Critically Endangered” treasure that depends entirely on us. By choosing to value the “wet bits” at home, in our neighborhood or on our land, we aren’t just saving a bird—we are ensuring our own communities have clean water and a buffer against the storms of the future.

Don’t wait for the water to clear on its own. Be the one who starts.
