The South Island of New Zealand has had a long history of mining of orogenic gold deposits and the placer deposits that have accumulated from erosion of those deposits (Williams 1974). Research over the past decade has provided some new insights and understanding of the processes of formation of the orogenic deposits, and this new research provides a context for ongoing exploration activity. This paper outlines some of the general findings of the research effort and provides some indicators for specific features of the orogenic deposit formation that are worthy of including in an exploration strategy.
