Why did it take so long?

Stuff reports:

A driver with more than 100 traffic violations and a dozen criminal convictions has had his taxi licence revoked.

Why so long? Shouldn’t it be revoked after say one conviction and/or three or four traffic violations?

Raj Naresh, a 40-year driving veteran, has been stripped of his passenger licence by the NZ Transport Agency as he is no longer considered “a fit and proper person to be a taxi driver”.

Since starting as a taxi driver in 1975, Naresh has racked up 110 traffic-related offences, 12 criminal convictions, a further three criminal offences where he was discharged without conviction, 17 regulatory offences, 50 documented “complaints about his activity and behaviour as a taxi driver”, and six transport licensing sanctions.

Astonishing.
