During his career Professor Hunter has held visiting positions at the Department of Statistics, University of North Carolina at Chapel Hill, (1973, 1988, 2001), Department of Industrial Engineering and Operations Research, Virginia Polytechnic Institute and State University, Blacksburg, (College of Engineering Visiting Professor 1980, 1987) and has been an academic visitor at the Department of Mathematics and Statistics, McGill University, Montreal, (1988), Mathematical Sciences Institute, Cornell University (1988), Statistical Laboratory, University of Cambridge, U.K (1992), Department of Industrial Engineering, Texas A & M University (1992) and Department of Statistics, University of Oxford, U.K., (2002).

In 1992 he was awarded a Claude McCarthy Fellowship to visit universities in the U.S., Canada, United Kingdom and South Africa.

In 1992 he was the Distinguished Lecturer in Applied Probability, Department of Industrial Engineering, Texas A & M University.

Served as Chair of the Royal Society of New Zealand Committee on Mathematical and Information Sciences (1997 – 2002). For his services to the Mathematical Sciences he was awarded a Bronze New Zealand Science & Technology Medal in 2003. In 2006 he was the recipient of the Campbell Award, the highest award given by the New Zealand Statistical Association, “to recognize his contributions to statistical research and education, and his services to the profession of statistics“.

Appointed to the Advisory Board of Christ’s University in Pacific, Nuku’alofa, Tonga in 2015.
