In 2008 he competed in a new Mitsubishi Evo IX, winning the New Zealand title. He also finished 13th overall and fourth in PWRC on his home round of the WRC. In 2009 he retained his New Zealand title, and also qualified for the Pirelli Star Driver Asia-Pacific final at the 2009 Rally Australia. Paddon was the fastest of the drivers on the opening day's stages, meaning he won the Pirelli Star Driver scholarship, giving him a fully funded programme for six events of the 2010 World Rally Championship season.

Paddon also won a $50,000 International Rising Stars Scholarship run by Rally of New Zealand, giving him the additional funding needed to complete a full 2010 PWRC campaign in addition to the PSD events.
