Its a hard one. Make them increase bottom end wage rates, and they move offshore. Ironically they are here as offshore.
Allow them to keep wages low, so the employees stay employed and we encourage NZ as a low wage economy.
Unemployment is low here, that encourages lower wages, thats basic supply and demand, so there is weight that these employees would rather have this low paid and low skilled employment than go to the workplace where jobs are hard to find. They can however keep looking around. Those that want a better paid job will find it in time, if they look around. Bit harder if they all get laid off at once if Sistema bug out.
