Lodge dispute resolution with PRTB asap. It takes about 8-10 weeks before they will get to it. If they find in your favour, they will impose an order for him to make good any monies he owes you. Do not taint your position by doing anything illegal.I would not under any circumstances change locks or get heavies involved.
Hopefully talking to him may help him decide that it is in his best interest to move on. I would be forceful but remain within in the law. Let him do the talking, find out why he wont move on. Have a read of some negotiation tips off the net.
Best of luck with it. I think the Residential tenancies act should be amended to capture the fact that people sometimes dont pay their rent. Lobby your politician.
