[2] Nansen's biggest fight of her career was against Melissa St. Vil for the vacant WBC Silver female super featherweight title on the Kali Reis vs. Maricela Cornejo undercard.
In 2016, Nansen was appointed as the number one contender for the New Zealand National (NZPBA Version) Super Featherweight Title, which was then held by Rebecca Jennings.
Shortly after the bout, Nansen's camp was approached by the officiating supervisor and it was revealed the scorecard calculations were added up incorrectly.
Nansen apologised to the official and the sanctioning body, which accepted the apology after lengthy conversations and suspended her from its events for 12 months.
