How can i go fast and easy way to New Zealand and work there?

Take a look at http://www.immigration.govt.nz
and http://workingin-newzealand.com
Explains what visas you should get and how you go about it etc...

...or you can try a working holiday http://www.bunac.org/nz
provides work/travel programmes that give participants the opportunity to live and work in NZ.

Get a passport from your country and work permit from New Zealand, air ticket of course will help you reach fast!!!

New Zealand is a country

Depends on what you have to offer.
If you have education, skills, and/or training
the country needs,
then it's very likely you will be sought after.
Some places will even pay your work visa fees
and travel expenses if you are the person they need.
Check out the skills shortage list on the immigration site
mentioned earlier by K Bear.

Don't have education, skills, and/or training?
Well then they can always use manual laborers to work picking fruit.
Sorry, you probably won't get paid transportation for that.
Some orchards have modest (bunkhouse) worker accommodations
you can live in for a small fee.

There actually is no "fast and easy way" to NZ
unless you are jumping the ditch from OZ.

Good luck!

NZ is always looking for experienced, highly skilled and university qualified workers. Sometimes; such is in the medical and accounting fields, you may have to retrain and gain NZ Qualifications, depending on where you are migrating from. It would pay to check out positions of work with which you are interested in, to see if there are jobs available, and go from there.....Good luck!
