Capt. GD Hamilton was one of the early British settlers who, in the late 1800s, stocked New Zealand Rivers with brown and rainbow trout. Capt. Hamilton originally hailed from the north of England, and wrote the first book on angling in New Zealand, of which I have a facsimile copy of his 1904 edition. It is entitled ?Trout fishing and sport in Maoriland?. He felt, as do many still today, that fly selection was something that was made to be far more complicated than it is.
