WTF ! This sounds like politicians talking, they say one thing one minute and then another the next.
New technologies and new forms of electronic money are always emerging.
These include:
stablecoins
cryptoassets (like Bitcoin or Ethereum)
decentralised finance.
Digital cash can take advantage of new innovative features like smart contracts.

Some other forms of digital money, like cryptoassets, are not denominated in New Zealand dollars. If a lot of people use them, it can pose a risk to our economy, the New Zealand dollar, and our monetary sovereignty. Monetary sovereignty is important because it means that New Zealand can:
independently manage its money
set interest rates
make decisions without being overly influenced by external forces.
