100 Kina Reduced Size

Papua New Guinea's decision to introduce a reduced-size 100 Kina on polymer came well after neighboring Pacific nations had already standardized on similar formats — the Bank of Papua New Guinea was notably conservative about resizing its higher denominations. Note Printing Australia has handled PNG polymer production continuously since the late 1990s, meaning the technical relationship predates this issue by over two decades.

The transparent window is integrated directly into the polymer substrate rather than applied as a patch — a distinction that matters for authentication in a country where high-denomination counterfeiting has been a documented concern.
