Hi Paul and Liz,
Have you checked out the NZ government website for immigration? If not it can be found at
Living and joining family in New Zealand. That will give you an idea of visa type and ages.
Depending on where you are from have you thought about contacting a migration agent (the first consultation is usually free), or going to an expo? If you are near Leeds in the UK, I know that the Emigration group are doing a presentation on May 11th -
Welcome to The Emigration Group Website - A complete migration service for New Zealand and Australia. They helped us to get into Australia - yes so I'm your future neighbour
Regards,
Karen
