Grant Robertson is the AIR N.Z. Govt appointed representative as you probably know. Of all the crowd in this labour Govt he probably has his head screwed on the best.
It will become obvious a major rights issue is the best way forward but it might take some time for him to get his head around it and work out the optimum methodology behind pricing. Yet another extension to the trading halt so all this can be ironed out first, wouldn't surprise me.
