Relocation to New Zealand by Wealthy
The news article states that New Zealand is experiencing an "exodus of over-30s," directly contradicting the prediction that wealthy Americans would be relocating to New Zealand. This indicates a net outward migration, rather than an influx, from the country.
What would prove this wrong
Within six months there is no observable increase in wealthy American relocations, real estate purchases, or investment inflows into New Zealand.
