I don't think anyone here is going to be able to give you a definite answer. The NZ government have been and are making up ways to deal with the Covid-19 crisis as it goes along, many of these cutting across existing arrangements which work in normal times.
In natural justice, I think it would be very unfair for it to be held against any resident applying for PR, who took the COVID-19 Income Relief Payment because s/he found her/himself jobless due to the crisis, this relief payment being designed specifically for that situation.
If you're after
certainty on this matter, you will need to ask INZ and/or WINZ. You may well discover, though, that nobody has yet thought to write up a decision.
