"After this break I trialled again for the Tall Ferns and in 2010 I made the team again. I re-trialled in 2011 and 2012. I have played for the Tall Ferns now for three years in total.
"If I am successful at my upcoming trials this year, 2013 will be my fourth year playing for the Tall Ferns."
In a later affidavit she said "unfortunately, and after serious consideration" she made the "hard decision" to pull out of last year's squad.
Katu does play representative basketball but Basketball NZ says she has never made the Tall Ferns. She trialled once in 2009 or 2010 but had not been on the radar since then.
Chief executive Iain Potter said his organisation had the ability to bring disciplinary action against people for bringing the sport into disrepute, but hadn't considered it in this case.
Another affidavit from Katu's former employer Natasha Suaalii, the centre manager of the Agape Aoga Amata preschool, says staff members of the centre had "supported some of her games when she has been playing for New Zealand." But yesterday Ms Suaalii said she had not actually seen Katu play for her country.
Katu also wrote in an affidavit: "Although basketball is my first love, I also represent New Zealand in touch rugby and volleyball and tag."
The national bodies for these sports could find no record of Katu playing at the top level.
Katu said she attended Oklahoma University on a basketball scholarship, and had been offered one at North Carolina University.
A spokesman from North Carolina University said she was never offered a scholarship there and a spokesman at Oklahoma University could find no record of her being a student there.
Katu was unavailable for comment.
