Sorry, I didn't spot your post sooner.
Rockwell has about 50% of the PLC market here in NZ, rising to closer to 65% of the larger systems.
The rest of the market is pretty evenly divided between Modicon, Seimens and Omron with a smattering of also rans like Klockner Moller.
The bulk of our industry is roughly in order of importance:
Food Processing/Dairy/Meat Processing
Infrastructure Electricity/Water
Forest Products/ Timber/ Pulp Paper
OEMS Packaging/Conveyoring etc.
A small but significant Oil&Gas industry and one modest steel mill, one decent sized Aluminium smelter. In terms of manufacturing NZ tends to have just one or two modest sized plants in any given industry. Bear in mind our population is just 4m so there are relatively few large scale opportunities here.
What is missing are the large assembly industries like automotive or large raw materials like metals, chemicals etc.
As for work...welcome aboard. You will find the pay rates a lot lower than you are used to, but on the other hand there is at most parts of the economic cycle a chronic shortfall of capable PLC people here.
