If you’re a professional and aged under 55, you can apply for a resident visa under the Skilled Migrant Category. You can make a quick self-assessment of your points from the New Zealand Immigration website: https://www.new-zealand-immigration.com/immigration-points-guide/

Please note that the cut-off point for selection varies based on demand and immigration policy. At present, applications that are on or above 160 may be selected for the next step which is Invitation to Apply (ITA). However, the applications with a job offer in New Zealand are more likely to select for ITA than the applications without a job offer.
