You might associate "duelling" with the American Wild West: leather chaps and cowboy hats and one-shot pistols on a dusty shanty-town road against a blood-orange sunrise...
But New Zealand has its own particular history of duelling - more than three-dozen took place between 1830 and 1935, and at least two people were killed.
Dr Donald Kerr is the Special Collections Librarian at Otago University, and he's written a book on the country's duels called The Smell of Powder. He tells us what the duels entailed.
