Ah, right - now I understand.
This is for someone who gets Residence with the Section 49(1) condition mentioned before - that is, within three months of arrival in NZ, they must take up the job offer that was part of their application, and then work in it for three months, and show proof to INZ that they have done that and are still employed, in order to get the condition removed from their Residence visa. The mention of 'seven months' is made up of three months after they get to NZ + three months in the job + one month's leeway for getting in touch with INZ.
But as I said before, since you're already in NZ and given the length of time you have already been working in that job, it is unlikely that any such condition would be put on your visa.
