Should we know if candidates are criminals?

Newshub reports:

Momentum is building in Parliament for more transparency around who the public is voting for in local body and parliamentary elections.
National MP Matt King has put forward a Members’ Bill that would require the disclosure of candidates’ criminal convictions if the offences resulted in two or more years’ imprisonment. 
The proposal wouldn’t disqualify people from becoming candidates or affect people with convictions concealed under the Clean Slate scheme, or if there is a court order or other legal requirement that prohibits publication.

That seems a reasonable threshold. The offending would have to be very serious to result in a jail term of two or more years.

UPDATE: The Newshub story was incorrect on the threshold. It is anyone convicted of an offence with a maximum penalty of two or more years – regardless of what their actual sentence is.
