The plan would see a wahaora, or traditional māori welcoming area, installed at the entrance of Pūtaringamotu.
The entrance would be next to Dean's cottage, the oldest building on the Canterbury plains, built for the Scottish pioneering brothers William and John Deans, in 1843.
The Deans brothers were the first European settlers of the area and rented the land from Ngāi Tūāhuriri.
Trust Board member and manawhenua, Nigel Harris, said the relationship between the settlers and the iwi is an important time in history.
"It’s a really cool interaction to be celebrated and my feelings are that because it’s such a significant piece of ngahere [forest], it’s like the jewel in the crown for Canterbury."
The Riccarton Bush trust have maintained and managed the forest since it was appointed to them by the government in 1941.
The Trust are working alongside Ngāi Tahu's consultancy agency, Matapopore, to deliver the upgrade effectively.
"The enhancement processes that they’re looking at doing is only just going to assist the wider community in educational input," said Harris.
Harris said Pūtaringamotu/Riccarton Bush is an important part of restoring the cultural disconnect between nature, and people living in urban areas.
