Debbie Tanner (now Hansen; born 8 October 1982 in Auckland) is a triathlete from New Zealand, who placed fourth at the 2006 Commonwealth Games in Melbourne, and competed at the 2008 Summer Olympics in Beijing.

[1] Tanner was admitted to the national team when she first competed for the junior category at the 2000 ITU World Championships in Perth, and since then, she had proven her tenacity, endurance, and positivity to reach into a higher level within the international scene.

In 2006, Tanner qualified for the 2006 Commonwealth Games in Melbourne, and was selected to the national team; however, her training and willpower was insufficiently enough to win a medal, as she finished fourth in the women's triathlon, just behind her compatriot Andrea Hewitt.

[3] Despite her sudden and disappointing result, Tanner recaptured her success and triumph at the ITU World Triathlon Cup in the same year, as she clinched her major international title in Ishigaki.

She also performed consistently by taking part in seven competitions of the Dextro Energy World Championship Series, where she only obtained a top ten finish, without winning a single medal.
