Hi Omarus,
Welcome to Move to NZ.
I would think applying for teaching jobs would be the better option if you want to work in NZ, as teachers are in short supply. ?It is often very difficult to get a job offer from outside NZ and, if they can afford to do it, some people travel to NZ on a Visit Visa to meet employers face to face and have more success that way. ?They either go on a holiday to look for work a short while before they want to immigrate or they enter NZ with the intention of looking for work and then staying there. ?Once you have a job offer you can apply for a Work Permit which shouldn't take very long to come through - only a few days, although some people have had them the same day as they applied.
I'm not sure, but I think you may have to be registered as a teacher in NZ before you can work as one. ?Another thing to think about is whether your teaching qualification will be recognised in NZ. ?To apply for residence your qualifications must be assessed by the NZQA if they aren't from a recognised college or university.
If you prefer to go to NZ to work on a farm you could enter NZ on a Visit Visa, look for work and then get a Work Permit to allow you to work legally. ?I really don't think that farming would enable you to get residence though, as your job needs to be on the Skills Shortages List and you would need to be qualified in some way.
I don't think it's as easy to get residence in NZ as just working for 2 years. NZ is only interested in granting people residence who have special and much needed skills.
