I'm still on the case

.
Here's another bit about work experience from the NZIS Operations Manual. Jeez, there's stuff all over the place in there.

It doesn't mention anything about the 2-year rule on here, but I doubt very much you'd be able to claim points for anything less than 2 years .
SM11.10 Requirements
See SM11.10 Effective 24/07/2006
See SM11.10 Effective 13/12/2004
See SM11.10 Effective 17/12/2003
Work experience is recognised and qualifies for points if:
a. it is relevant to the principal applicant's* current skilled employment in New Zealand or offer of skilled employment in New Zealand; or
b. a visa or immigration officer is satisfied that it is skilled work experience because it required, or enabled the principal applicant* to gain, considerable specialist, technical or management expertise; or
c. it is relevant to the principal applicant's* recognised qualification (see SM14).
d. Principal applicants who do not have current skilled employment or an offer of skilled employment in New Zealand (see SM7) will only qualify for points for work experience if:
i. the work experience meets the requirements for recognition set out above; and
ii. that work experience was gained in a labour market that is comparable to the New Zealand labour market.
SM11.10.1 Definition: Comparable labour market
a. Work experience is assessed as being in a comparable labour market if it was undertaken in one of the following countries by:
i. a citizen or permanent resident of that country; or

SM11.10.5 Relevance of work experience to qualifications
Work experience is relevant to a principal applicant's* recognised qualification if a visa or immigration officer is satisfied that the qualification was:
a. an important factor in the principal applicant* being able to obtain work or continue or advance in the position or field of work in which they have experience; or
b. an important factor in a career path that has advanced progressively from the principal applicant's* pre-qualification work experience.
SM11.10.10 Relevance of work experience to an offer of skilled employment in New Zealand
Work experience is relevant to a principal applicant's* offer of skilled employment in New Zealand if an employer considers, and a visa or immigration officer is satisfied that:
a. the work experience is directly applicable to the employment offered; and
b. the offer of employment could not reasonably have been made if the principal applicant* did not have that work experience.
