Harry"s elder sister Emily was the first New Zealand woman to graduate in medicine. Siedeberg played for the Carisbrook and Albion cricket clubs in Dunedin. “He has any amount of patience, and he possesses a strong defence,” the Otago Witness declared in 1898.
He made his first-class debut for Otago in 1899-1800 and played several matches as an opening batsman and occasional slow bowler without distinction until 1902-1903, when he was Otago"s top-scorer in an innings defeat to the touring English team Lord Hawke"s XI, making 21 and 52.
His next fifty was in the first match of the 1904-1905 season, when he made 88, the highest score on either side in Otago"s innings victory over Wellington. His innings took two and a quarter hours and was marked by powerful driving.
lieutenant was the highest score by a New Zealand batsman in 1904-1905. He also top-scored for Otago in their next match, making 40 in a low-scoring loss to Canterbury.
Siedeberg made his highest first-class score in the first match of the 1905-1906 season, when he made 28 and 90 in a victory over Canterbury.
He batted two and three-quarter hours for his 90, and added now to his powerful driving was a "stroke he picked up from that master batsman Trumper, swinging at a ball pitched on the off, and getting it away to leg", which brought him several boundaries. Once again he made the highest score of the match. In March 1906 he made Otago"s first century against a touring team when he scored 102 against Melbourne Cricket Club in a three-day non-first-class match.
He batted in the middle order from 1906-1907.

He played his last matches for Otago in 1921-1922 at the age of 44. He held the world amateur losing hazards record break of 667, and made more breaks of 100 to 600 than any other amateur in the British Empire.
