The Verdict: Not eligible
New Zealand does not sell citizenship at any price. If a second passport is the goal, look at other countries; if residence in New Zealand is what you want, go back and choose that answer.
Investment buys residence, on light terms: NZ$5 million for 36 months with 21 days in New Zealand under Active Investor Plus Growth, or NZ$10 million for 60 months with 105 days under Balanced.
Citizenship needs five years holding residence, 1,350 days in New Zealand and at least 240 in each year, plus English, good character and an intention to keep living there. Money does not shorten any of it, so a light-touch investor is not partway to a passport.
