I would be very grateful for any advice anyone can give me. Me and my wife and kids are seriously looking at emigrating to NZ, probably as permaneny residents. Does anybody know of any clever ways of getting parents there also before the three years of residency are up? Also, if they could only visit for the first 3 years, what amount of time can they stay in the country each year? What are all the options? A further possible option is for them to apply on the business migrant option. Does anybody know what the general rules are with regard to type of business, projected turnover etc. Could they for example use opening a B&B as a business option? Thanks in anticipation
