Hi Guillermina

to the forum.
Would I be right in saying that you only want to visit and work in NZ for a certain time rather than going there to live permanently? To live permanently you would need to apply for Permanent Residency and, for that, you need to have job skills and qualifications that NZ wants. If you only want to visit and work and you're 30 years old or under, you could trying applying for a
Working Holiday Visa . They are only valid for either 12 months or 23 months but, for some of this time, you have to appear to be on holiday.
Tauranga is a tourist spot so, by going in November, you will be there at the start of the season and may be more successful in finding work in your line.
