Please, be calm and take the time to read all the relevant information. At the moment, you are almost sounding as though you WANT it to be impossible to get this visa - whereas, as previous posters have told you, it is almost certainly going to be very straightforward.
Your employer has to complete and supply this form
http://www.immigration.govt.nz/NR/rd.../0/INZ1113.pdf to INZ (as you will see here
http://www.immigration.govt.nz/migra...y/studytowork/), and it covers the points you have raised in your last post. Notice, that form is a multi-purpose one, and in the case of a Post-Study Work Visa, there are parts, including that about the labour market test, that do NOT apply. Talk it all through with your employer when you have read up about the necessary details. He wants you enough to have given you a permanent job, so I'm sure he will be willing to put his evidence in the best possible way to make it easy for INZ.
