It looks to me as though you are right in that you should investigate the requirements for yourself, and not necessarily believe what this agent is telling you.
Some things to look at.
1) With a job offer, your husband only needs a minimum of 100 points to have his EOI selected at the next draw.
2) Procurement Manager is on the List of Skilled Occupations. The requirements to be met are as follows.
Requirements to claim points for skilled employment (Category A)
A relevant recognised qualification which is at, or above, the qualification level on the New Zealand Qualifications Framework. The qualification must correspond to the skill level indicated for that occupation in the Australian New Zealand Standard Classification of Occupations (ANZSCO)
OR
The relevant work experience that the ANZSCO indicates may substitute the required qualification
OR
The relevant requirements specified in the Long Term Skill Shortage List (LTSSL) for your occupation (if your occupation is included in the LTSSL)
OR
Five years of relevant work experience.

ANZSCO
http://www.abs.gov.au/ausstats/abs@....ement+Managers wants a bachelor's or higher qualification, or at least five years' relevant experience can substitute.
3) Here
http://www.immigration.govt.nz/opsmanual/6954.htm are all the regulations for SMC. SM6 has a chart of all available points, and the last column shows which other section to look at for the detailed requirements for claiming those point.
4) If it's going to work for the company to transfer your husband, their NZ operation has to be working out of NZ, registered there as an employer.
5) Many people with a job offer, with an employer waiting for them, put in for a temporary work visa or WTR in the first instance, because it takes less checking and can be processed much more quickly than an application for Residence under SMC, so the applicant can be there and working, while the Residence application, put in at the same time, can tick along taking the time it takes while they're already in NZ.
