She said tamariki were presented with a little greenstone adze when they headed off to school, so it was fitting an old greenstone adze was unearthed during the excavation.
Now two little whare for the tamariki to play in and a fire pit adorn the site, and a mural has been painted on the wall.
Wadsworth said the playcentre planned to use the fire pit for family nights and sausage sizzles.
She said the playcentre was planning an official opening for the new site soon.
“It has been a long time coming. It has been a project over more than 10 years.
"Over that time we have been fundraising and planning, and there have been delays and hiccups, and we have been consulting with different experts and iwi representatives.
"There has been so many people in the town who have been involved, including former playcentre families. It is going to be a big community opening."
Rawiri Manawatu from Te Rūnanga o Kaikōura offered advice during the project on the heritage of the area.
The project was also supported by the Kaikōura Lions and the Kaikōura District Council, while local businesses and volunteers had pitched in.
Wadsworth said the playcentre was open three days a week, with around 50 children attending the weekly sessions.
Te Rūnanga o Kaikōura chairwoman Hariata Kahu said a large number of archaeological sites had been found in the area.
Archaeological findings had confirmed a Ngāti Kurī presence in Kaikōura going back more than 700 years, but recent discoveries suggested settlement as early as 1000 years ago, she said.
