Craic and Birmanboy, the market is going to solve all the unemployment problems? It will evolve some interesting jobs to match the skills of the NZers out there, all by itself? The market cares mostly about profit, and profit can be easily obtained by dropping back on staff in many areas.
I've seen Spotless operating from up close a few years back, and I was unsettled.
Here's a glimpse of their NZ website. All these services, they'll tailor a package to suit the premises. This means they'll have to learn all about some quite specific tasks that engineers and food providers etc do, add that into their task list, and of course the accountants at these places think that's a great idea. They start out cleaning, then move into many other areas. This displaces other contract firms and employees, and of course there will be some loss of local experience and knowledge. The costs will be lower, but the level of service has to drop. Ultimately you'd have to expect that something major will happen, that means any savings were a false hope in the longer term. This will not worry Aussie-owned Spotless.
