"With our Karamū Restoration Project, we are focusing on planting native species that will shade the stream and lower the water temperature for the habitat. It will also keep stock away," said Bostock.
The plan was to complete the work as sustainably as possible.
"All the fence posts we are using are recycled from our organic vineyard. We haven't used any chemicals or sprays to prepare the area for planting and we are using hay mulch as fertiliser," he said.
Hawke's Bay Regional Council chairman Rex Graham welcomed the initiative.
"It's outstanding to see Hawke's Bay companies and community groups getting in behind us to help clean up our waterways. Restoring the Karamū is doable, but we can't do it alone."
The first native planting day involving Bostock New Zealand staff, family and friends would be held on Sunday, June 17, and the public was invited to join in.
