"I would like to thank Snow Sports NZ and the NZOC for their amazing support during this rehabilitation, it truly means the world to me to have such a great team in my corner. I would also like to thank the New Zealand public for their support over the years and I look forward to representing you all in the future.
"I wish the best to the rest of the team and I look forward to supporting each of the incredible athletes representing our great nation."
