New Zealand’s Customs website "explains":
“Making an arrest without a warrant can now be done with no limitation to timeframe.”
Congratulations, Kiwiland -- you are now a rogue country!
It's now "official" that one does not have any rights whatsoever at the New Zealand border anymore. Good luck with all your tourism income :)
Agents can search your electronics without cause, and fine you for refusing to give out your password. They can collect, store, and share any of your biometric data they want. (This is just great, isn't it...?)
They can arrest you without a court order, and hold you for as long as they like. (Great again. Very modern, too...)
And as a little "extra", keep in mind that the Kiwis are part of the "Five Eyes" group that unlawfully shares surveillance data among the US, Canada, UK, Australia, and New Zealand in violation of your individual right to privacy, Free Speech, and similar...
For a visualization of the Five Eyes Alliance, just look at a map of Oceania from George Orwell’s 1984—the dystopian classic portraying the ultimate authoritarian police state.
Habeas Corpus, the right to be secure against unreasonable search and seizure, the rights of the accused… these are quickly becoming lost to the memory hole of history.
