The natural world here is steeped in Maori legend and we're told never to divide a flax plant, which has a gel at the base of its outer leaves that can be used for cuts, wounds, sprains and bruises.
"According to tradition, the outer leaves of the flax plant represent the ancestors or grandparents, the next layer of leaves represent the parents and the new shoots represent the children. If the plant is halved, the family is too," warns Helen.
We stop to be shown the kawakawa leaves and are reminded to always choose the leaf with the most holes, because insects go for the most nutritious leaves.
After about an hour, we make it out of the bush at the top of Oceanview Rd before heading to Alison Park, with its sculptures, such as Paul Radford's Flotsam rowboat and Peter Lange's two brick and ceramic chairs. Before we arrive at the end of the walk, in local resident and distiller Jill Mulvaney's (alembics.co.nz) garden, we're given our last piece of advice as Helen picks up a giant leaf and tells us it's bushman's toilet paper.
Jill has been baking orange and calendula muffins and distilling from Portuguese handcrafted copper stills to make us nettle and lemon drinks. It's welcome relief after our walk and the distilling equipment set-up in her well-maintained backyard is impressive and makes a very pretty setting.
It feels like we've stumbled on a special cafe no one else knows about and, in a way, the walk offered the same feeling - we've found a more scenic route from the wharf to Oneroa and discovered natural health tips along the way, just by stopping to smell the weeds.
