Not sure about vincent but think youll find Mt Cook are about the only ones hiring at the moment. Eagle have a few guys off an earlier ground course waiting to start although it looks like the numbers are looking healthier than expected so those guys/girls may have a small wait. Think youll find Nelson overstocked with the fleet replacement well underway so wouldnt expect much to happen there for the foreseeable future.
Short of it is that apart from a few going to Cook, there is not a large exodus of anyone to anywhere.
