Comrie Researcher IN Dunedin

Greetings Comrie Researchers - my question is rather unusual. My wife's grandfather was friends with a Mr Comrie in Wanganui in the early 1900's. At some point in the last 20 years my mother-in-law gave me the name of a Comrie researcher in Dunedin who had played a part in a reunion in Christchurch. Sadly I've lost the contact details of that gentleman. Does anybody know who that might be? Thanks.
