Interesting question! I haven't had dealings with this exact situation, where the secondary applicant gets a job offer but not the main applicant. I rather think that the answer is "No, it won't". How many points would you have if you put in an EOI with the secondary applicant as the new Primary Applicant? If it's over a 100, this would be worth considering. Might be worth a call to INZ just to check. One other option is that you head to NZ on a Work Visa based on the job offer, get partnership work visa for the partner and appropriate visas or nay children. Once there, the other person would be in a much stronger position to get a job offer.
