- As president of the Art Galleries and Museums Association of New Zealand (AGMANZ), McKenzie writes of the great progress and development of New Zealand museums and art galleries in this birthday issue celebrating the first forty years of AGMANZ. McKenzie points to issues that need to be faced in the future if museums are to ‘truly reflect the nature of New Zealand society’, and particularly stresses the need to encourage greater Māori involvement in the museum profession.

- McKenzie discusses the implications and possibilities of biculturalism in the museum world - a debate she notes was triggered by the Te Māori exhibition which had Māori involvement at every stage of the project. McKenzie affirms the contribution of Dr Michael Ames, Director of the Museum of Anthropology at the University of British Colombia in Canada, in his studies on the treatment of indigenous peoples.

- McKenzie asserts that AGMANZ must continue to ‘provide the forum for debate’ and adds that it ‘must be the catalyst for the development of new ways of seeing and understanding. It must and can provide the leadership in developing bicultural partnership between Māori and Pakeha. We must strengthen our association, our profession and our professionalism to ensure that our museums are relevant to all the people of Aotearoa New Zealand into the 21st century.’ McKenzie gives an account of the work of executive officer, Cheryl Brown, and the Council during 1988-1989.

- An edited version of McKenzie’s address to the International Council of Museums (ICOM) Committee for Conservation meeting held in Sydney from 6-11 September 1987.

She discusses New Zealand’s recent history of conservation and the progress made between 1972-1986, and notes three events that have stimulated increased attention to conservation issues: the Te Māori exhibition, the decision by Parliament to develop the National Museum of New Zealand, and the establishment of the Cultural Conservation Advisory Council to the Minister of Internal Affairs.
