Given that you have not been in New Zealand for over 2 years now, you are unlikely to meet the criteria for a further variation of travel conditions (see
RV3) or a second or subsequent Resident Visa (
RV4). (Read the immigration instructions that I have linked, they will give you more information on this -- and also, read the
INZ 1176 guide.)
There are two scenarios that may save you: if you are the partner of a New Zealand citizen (RV3.20.5 / RV4.20.1) or if you are seconded overseas as part of your New Zealand employment (RV3.20.10 / RV4.20.5).
If neither of those two scenarios apply to you, you have only one option: return to New Zealand before your travel conditions expire. Otherwise, you will need to apply for a new Resident Visa.
