That chase began badly when outstanding opener Lega Siaka was caught behind from the bowling of Mohammad Naveed on the first ball of the innings. Wickets continued to tumble and PNG were soon reduced to 45-5, before slumping to 130 all out.
Elsewhere, rain denied a grandstand finish between Kenya and Hong Kong in Rangiora but, after the Duckworth-Lewis calculations went in their favour, Kenya wouldn't have been complaining. Jamie Atkinson's captain's knock of 85 helped Hong Kong to compile 254-8 batting first.
With Kenya needing 32 runs from 28 balls with six wickets in hand, the match seemed set for a nail-biting conclusion, before the heavens opened and the African nation were awarded a 10-run victory.
In the day's other match at Lincoln, rain interrupted Namibia on 59-2 after 12 overs, chasing Scotland's total of 279-9.
