The room was redecorated in 1955 by Ngāti Tūwharetoa carvers and chiefs. Red and black kōwhaiwhai were added to the decorative ceilings and the cornices of the room, and tukutuku extended all around the walls. Reproductions of Te Tiriti o Waitangi were cast up on to the walls alongside portraits of distinguished Māori members of Parliament: Sir James Carroll, Te Rangi Hīroa—Sir Peter Buck—Sir Maui Pōmare, and the Hon Sir Apirana Ngata. There were also portraits of Sir Eruera Tirikatene, the Hon Matiu Rata, Iriaka Ratana, and the Hon Whetu Tirikatene-Sullivan, which have been added since.
