This is an excellent move. The Supreme Court ruled that ban violated NZ’s bill of rights, and the Waitangi Tribunal also has stated that the ban breaches the Treaty Of Waitangi.
Voting is also something that’s done outside of prison, so it can hence be part of rehabilitation to normal society – albeit a very small part.
Sadly, however, the ban is not lifted on all prisoners – just those that have committed offences resulting in a sentence less than three years. So this doesn’t go far enough. The next step needs to be giving all prisoners the right to vote.
However, it is a start. Good on the government.
