I have already applied for Skilled Migrant Category Resident Visa.
Immigration says.

Before we can invite you to apply, we’ll first need you to send us an Expression of Interest (EOI) telling us about your employment in New Zealand, work experience, and qualifications. If your Expression of Interest is successful we’ll offer you the opportunity to apply to live and work in New Zealand indefinitely.There is a points-based system with is a minimum amount of point to be selected.
Currently, we are only selecting EOIs with 160 points or above.I currently I have 125 point.

Or getting a job offer too.

So, If I get a job, I can live and work in New Zealand indefinitely.
