Tuhia he tomokanga mō tēnei wāhanga - I reti atu a Dubberley i te whakataetae i te tau 2006, ā, i te marama o Whiringa-ā-rangi o taua tau i tohua hei kaiako matua o te kapa Rugby Wheelchair Rugby o Ahitereiria. I whakangungu ia i te kapa ki te mētara hiriwa i nga Taakaro o Beijing 2008 me te 2010 World Wheelchair Rugby Championships. Kei te whakarite ia i te kapa mō ngā kēmu o Rānana 2012
He aha? I whakangungu ia i te kapa whutupaoro tiamana a Ahitereiria i te 2012 Summer Paralympics, i haere i roto i te whakataetae e rima-ra kaore i hinga, ka wikitoria i te mētara koura. Ko ia te kaiako matua i te 2016 Rio Paralympics i wini ai te kapa i te Koura.
