"The commemoration should appeal to those who are interested in Rangitikei and New Zealand history and conservation," she said.
"His ideals continue today throughout New Zealand with the Robert C Bruce Trust."
Since 1968, over $400,000 of trust funds have been donated to university research into New Zealand forests, including the restoration and maintenance of native forests on public land.
The University of Auckland, Massey University, Victoria University, University of Canterbury and Lincoln University have all been beneficiaries.
Among other projects, the trust funds were used to complete the road access, known as Bruce Road, to the Whakapapa area where the Chateau Tongariro and park headquarters are now located on Mt Ruapehu.
Ms Grant said people attending the event should wear suitable footwear for the short climb to the Bruce Memorial.
