This monograph is a compilation of four papers presented by Māori scientists at Turnbull House, Wellington, in November 2005. The papers were delivered as part of the Ngā Pae o Te Māramatanga Policy Seminar Series “Progressing Māori Development through Research”. Each of the scientists―namely James Ātaria, Elizabeth McKinley, Michael Walker and Shane Wright―has carried out pioneering work in her or his field and contributed to wider Māori enterprise and development.
