Nightmarch, foaled in 1925 was an outstanding New Zealand bred Thoroughbred racehorse known as The Kiwi. He won the New Zealand Derby and Dunedin Cup as a three-year-old before going to Australia where he became the first horse to win both the Melbourne Cup and Cox Plate in the same year, as well as other Principal races.

He was by Night Raid, the sire of Phar Lap, out of the good racemare and broodmare, Marsa (1911) by Martian, a mare that traced to Manto. Marsa produced five foals, all of which raced and were winners.
