When anyone applies under the Skilled Migrant Category, if they are successful, it is a Residence visa that they get. Years ago, it USED TO BE called PR, but all the names were changed in November 2010. Nowadays, PR is a different visa that a person can only qualify for after at least two years as a Resident.
Whichever way you apply for it (Skilled Migrant, Family Category, Residence From Work from within NZ, after having a WTR (there are different kinds of those) for a couple of years...), the first 'forever' visa you get is called Residence, with travel conditions that last two years. After two years, if you have established commitment to NZ (various ways, but most frequently, spending half the time or more of each of those two years after activating the visa in NZ), you NOW are awarded Permanent Residence, which doesn't need any travel conditions.
