Ifwersen attended both St John's College and Auckland Grammar. He joined the new College Rifles rugby union club and was instrumental in helping the team win back-to-back junior championships in their first two years in ARFU competition. In 1912 he represented Auckland in provincial matches.
Rugby league career
Ifwersen then switched codes to rugby league, joining the Grafton club in the Auckland Rugby League competition. He played for Auckland before representing his club and made the 1913 New Zealand tour of Australia. He also played for the North Shore club.
Return to league
After the War Ifwersen returned to New Zealand and again made the New Zealand side. He captained the Kiwis against the 1920 Great Britain Lions tourists. Ifwersen also captained the side in four Test matches in 1919.
Rugby union career
In 1921 Ifwersen switched codes, playing rugby union. He immediately returned to the rep team, captaining the combined Auckland-North Auckland side against South Africa in his first game back and scoring the only try.
Ifwersen continued to play for Auckland between 1922 and 1938.
Ifwersen died in Auckland on 19 May 1967, having suffered considerably from football injuries during his old age.
Ifwersen was inducted into the New Zealand Rugby League's Legends of League in 2000. He was the first New Zealander to represent his country in rugby league before rugby union. This accomplishment would be unmatched until almost 90 years later by Sonny Bill Williams.
