Question regarding the NZ Visitor Visa for a US passport holder.

With the new remote work allowance officially allowed, I was hoping to settle in for a few years quietly in the outskirts of Hamilton to the NE, but might be hard if I have to leave for regularly for extended periods.

From what I can gather a Visitor Visa lasts 9 mos (single entry) and I can extend it (possibly) another 3mos, but then, no matter what, I have to leave the country for 6 mos before I can get another one.

Is this true?

I am on an American passport, am also on the Tier 1 Green List (either as ANZSCO 135111 or as ANZSCO 262112), not planning on working locally, but am 50 years old.
