| 备注 |
Papua New Guinea was among the early adopters of polymer substrate currency in the Pacific, and this 50 Kina was part of that conversion away from paper. Note Printing Australia — the commercial arm of the Reserve Bank of Australia — handled production in Melbourne, a relationship that has defined PNG's note supply for decades given the geographic and institutional proximity of the two countries.
The series ran across three signature combinations, the shift from Vele to Kamit in the governor position reflecting a change in Bank of Papua New Guinea leadership around 1999–2000. Signature variants on polymer issues of this period are sometimes overlooked by collectors who focus on design rather than administrative detail, but they represent distinct print runs.
