Unfortunately, PAR is not reliable. It is done ONLY by looking at the title of qualifications. If your EOI is selected and you have to fill in the ITA, you then have to give an IQA, which is arrived at by looking at what was studied, to what depth and for how long, which gives a reliable result which can be higher OR lower than the PAR.
This is the reason for giving points for a partner's recognized qualification.
SM17.1 Aim and intent
The aim of providing bonus points for a partner's recognised qualification(s) is to recognise such qualifications as an indicator of the likely contribution of the whole migrating family.
Therefore, it's the qualification itself that will bring the points, not preparedness to start working in NZ (for which registration will be necessary). The detail about requirements for the qualification is here.

SM17.5 Bonus points for a partner's recognised qualifications
Recognised qualifications (see SM14.5) held by the partner of a principal applicant qualify for the following points:
Level on the New Zealand Qualification Framework Points
three – must be on the List of Qualifications Recognised as an Exception (SM14.10.10)
four - must be recognised in SM14.10 (d) or (e)
five, or six 10
seven to 10 20
A partner's recognised qualification only qualifies for points under this provision if:
the partner is included in the application; and
the partner meets the English language requirements for principal applicants (see SM5.5); and
an immigration officer is satisfied that the principal applicant and their partner have been living together for 12 months or more in a partnership that is genuine and stable (see F2.10.1) and otherwise meets Partnership instructions (see F2.15).
