If you scroll to page 28 of this document - the very end - you'll see that it was issued in 2003. As the last poster says, this list is altered and updated as time passes, and at any time, the present version of it is here
http://onlineservices.immigration.go...nual/35171.htm (Appendix 3 of the INZ operational manual).
This list isn't talking about "likely" assessment levels, but the levels at which they
have been assessed. Therefore, if someone's degree - the exact title of it - is listed alongside the institution which they attended and which awarded it, and the year of the award is covered by the timing in the last column, then their degree does not have to be assessed again by NZQA for their visa application.
This list is not some kind of judgement on the educational establishments in other countries: it is not an insult if your university is not there. The reason why a degree appears on this list is because the course content has been checked out by NZQA, and they have found that it is very similar (and therefore comparable) to a degree course that is currently running in a New Zealand educational establishment. (This comparability is what is needed when claiming bonus points under LTSSL, for example.)
It can happen that someone finds their degree, and their university, on this list, but the dates in the last column stop before their graduation. In that case, they will have to get their degree assessed for IQA by NZQA. There are two reasons why this may happen. 1) The NZ university that did a similar course may have stopped running it. That means that there is no current NZ degree for the foreign one to be comparable to. 2) The foreign university may have changed its course content at a certain time, so that it then stopped being comparable to the NZ course.
