Wanaka and Colorado-based fly fisherman, guide, explorer, filmmaker and writer Derek Grzelewski tells Lynn Freeman about his latest book Fly-fishing in New Zealand, What you Need to know - a guide to getting the most out of a day on the river.
Derek has learnt from some of our best anglers and leads guided fishing tours, always reminding people to look up and admire the scenery as well as the trout.
New Zealand has a reputation for having the best and most challenging fly-fishing in the world, though Colorado isn't a bad stomping ground for outdoor adventures either.
