please suggest best way to apply NZLD work permit

Hi there

I am chef by profession currently working with International restaurant chain in UK. They also have some restaurants in NZLD but there HR work quiet independently.
I am interested to migrate to NZLD on work permit and later apply for PR.

Now i am confused that if i should apply international transfer within my company. what i know is in this option everything has to done by company even all the expenses and I am afraid if they will be willing to do all this up..??
Or
Should I ask for their help in getting the job there and then apply for work permit myself. which seems like a simple option not putting up to much work and expense pressureon the company.

Please Advise!!!
