Sir Toby said Te Arawa wanted to make sure the tribe's interests on the mountain remained intact and had requested to meet the local iwi on a marae, but the invitation was revoked last week.
He said since iwi members had already planned to take the trip and the buses were booked, they decided to go anyway, but instead took up an invitation to meet local Maori at a homestead in Whitianga.
A group of Te Arawa elders then travelled to Thames where Crown Chief Negotiator Chris Barker was meeting with Hauraki elders.
"We sat outside under the trees in a lovely spot and the Crown negotiator came out and talked to us."
Sir Toby said some of the Hauraki elders were uneasy about them being there so requested they meet again on a marae in the near future.
"That is what we wanted in the first place."
Sir Toby said the outcome was more successful than he thought it would be.
"We didn't want to go there and tell them they are wrong, we just wanted to put our case forward. It was a good success. It's not the sort of success that we can say the matter is settled. We are now waiting for them to invite us back so we can talk to them on the marae."
Sir Toby said Te Arawa had good relations with the Hauraki tribes, particularly Ngati Maru, because they made land available for Tuhourangi after the Tarawera eruption in the 1800s.
