There is no pleasant way to say this. At present, the way the NZ government has the immigration quotas set, EOIs with no job offer are only getting selected with 140 or more points. If there is no possibility of querying the IQA assessment on your wife's qualification to get those points back, then your EOI is going to be put back in the pool, where it has the right to be for six months from the date of submission. They won't go on processing it - they will put it back because it never would have been selected that week with only 135 points.
If you can possibly get a job offer, your EOI would be selected at once - selection only requires 100 points with a job offer.
