Unfortunately I don't think your wife meets the criteria for this category

Partners (from non-visa waiver countries) of New Zealand residents can apply for a Critical Purpose Visitor Visa if they are travelling with partner, and to have the application approved, you would need to meet the usual partnership criteria (ie living together in a genuine and stable relationship). Similarly, I don't think your partner would be granted a Partnership-based Work or Visitor Visa, simply because you won't meet the living together criteria.
The only options you have are to travel to your wife and live together for a decent period of time and then apply for either the CPVV (if you are travelling back together) or the partnership-based work visa, or you will have to wait until there is a change to the border restrictions and visa policy.
