Better, brighter Kiwi banknotes
The Reserve Bank has revealed brighter and better bank notes that will be hard to counterfeit and easier to check.
The new notes feature the same people, animals and plants, but the colours are brighter and the safety features are more sophisticated.
The new notes will gradually comes into circulation from October next year, when new $5 and $10 notes will come out.
The $5 note will feature Sir Edmund Hillary, but the orange colour on the note will be much brighter.
The Queen remains on the $20 note, but the green colour is much brighter.
The transparent windows on the notes will be larger and have "striking holographic features" that will make the notes easier to check and harder to fake.
The target date for release of the $20, $50 and $100 notes will be April 2016.
The Reserve Bank will remove old notes from circulation as the banks return them. Both old and new notes will circulate together and both will be legal tender.
The Reserve Bank said counterfeit rates in New Zealand were low, compared with the rest of the world but technology changes were making it easier.
"We need to stay ahead of the game," deputy governor Geoff Bascand said.
It will take up to 18 months before most notes in circulation are the new ones.
