Hi there
I moved to New Zealand in 04 after seeing an ad in the local paper here advertising for carpenters and joiners. Got a start with a small builder in Ashburton,a couple of hours south of Christchurch. It happened really quickly and travelled on a tourist visa and applied for a visa when I got there. It took maybe 5 hours waiting in the Christchurch office.
I personally found the carpentry side very boring as everything is produced in a workshop and the chippy just nails it together on site. On the joinery side, most of the kitchens are bespoke so plenty of cabinet work and the joiners make up all the door sets in the shop ready to be fitted on site. Slightly different way of doing things as they tend not to use architrave but have the lining proud and plasterboard slots into the back of the linings and a thin skirting finishes flush with the lining.
The biggest shock for me is how much things cost. Was only getting $18 an hour and cost of living is high. If you wanted to buy a powertool it would cost virtually the same as here in pounds. This applies to everything from vehicles to electrical goods to your weekly shop. We were spending nearly $200 a week on food which was almost a third of my wages. Petrol was nearly $1.50 a litre when i was there, god knows how much it is now.
My wife and I decided to come back as we had nowhere near enough disposible income as we did back in the UK.
You can also see why so many Kiwi's travel and earn £s,Euro's for a long time before they go back home.
I would recommend going to Australia over New Zealand any day. So many more oppertunities and more modern than NZ. Most houses in NZ older than 30 years will have no insulation in the walls and it can get to -5 in the winter with no central heating, only a log burner in the lounge.
It is a beautiful place and very much like the UK but 20 years behind the times.
I have lived in a lot of different places and would say Canada is the best option to emigrate to, then Australia. NZ is a long way down the list.
As you are only 19, I would definitely travel first to different countries to see what you prefer. Australia might need a bit more experience to get a visa aswell.
Hope I have been constructive enough for you. If you need anymore advice don't hesitate to PM me. I have been a chippy in Oz,NZ, Japan,Canada, the States and around Europe, now residing in the UK since 04.
