It starts exactly two years after the application is reopened to the public.
So, if you got kicked out in 2013, re-apply again come the 2015 intake when its' advertised.
I'm aware of a friend who attempted to beat the system an year later after he failed a stage (Psychomotor, I think) and he got caught at the Psychometrics stage of the 2nd application since his name was not on the new list. Though KQ HR takes time to clean up records on the KQ Career Portal, their internal records remain intact, it seems.
Just to be safe, you may contact HR on this policy.
