The wetland is already a popular place for shags and royal spoonbills.
The aim on Saturday is to add 3600 more native shrubs and trees around the wetland edge and on the island now accessible by bridges.
Ngaio does particularly well in the site on the coast, with two year old plants now well established and providing cover.
"The soft conditions are OK for planting, although we've decided not to plant in the boggier areas, but gumboots will definitely need to be worn - and bring a thermos as it's chilly with the onshore breeze and our usual coffee cart can't be there this time," warned HBRC Open Spaces Development Officer Stevie Smidt.
Children from PORSE home educators have also been planting on the Waitangi wetland site this week, following twenty groups from primary schools who planted as part of Ātea A Rangi Educational Trust's Matariki event last week.
Warm clothes and hats, sturdy footwear and gardeners' gloves will help volunteer planters stay comfortable in this coastal site.
Hawke's Bay Regional Council will provide the usual barbecue sausages as a thank you for the planters' efforts
