In those circumstances you should have applied for compassionate consideration straight after your exams, now with the result already out, they definitely will not take your application. So your only chance would be to see the lecturer and hope he is willing to change your grade. Before you go and see him, get some evidence (for example, some sort of statement from police saying someone stole items in your house) and hope for the best.
For your reference here is the University of Auckland website for compassionate consideration.
