The stylized fern-leaf motif, the Mâori koru.

The koru or (loop) is often used by the Mâori people of New Zealand/Aotearoa. It is based on the fern leaf that can be seen in the forest. A koru is used in Mâori art as a metaphor and symbol for new beginnings, creation, growth, strength, peace and harmony.
The Kiko Guided Tours logo alludes to this whakaaro (idea) and the "O" is a stylised representation.
This new unfurling fern leaf was adjacent to the track we walked on. I just love the simplicity of form.
