The name “Swampfrog” is inspired by our passion for wetlands, whakapapa and our native species.

Our Repo/Wetlands

Represented through the harakeke and peat moss at the feet of the frog. Narratives about the harakeke point to its relationship to our Atua, including important Atua Wahine like Hine-i-te-Repo (goddess of the swamp) and it is through them that we learn the rhythms of the environment and best ways to interact with it.

Our Whakapapa

Represented by the fan of the harakeke (Phormium tenax). Harakeke were an important resource utilised by our tūpuna, including our Pākehā ancestors who recognised its durability and toughness for rope building.

Our Valued Native Species

The frog in our logo is based on the highly endangered Archey’s frog (Leiopelma archeyi) which was once found across the Waikato. They are not swamp dwellers, preferring the moister areas of our native forests. We love frogs not only because they are rather handsome little things, but because they also represent the role our frogs can play globally as important indicators of broader environmental health.
