As Edwards' husband and her coach, Dave Edwards is perhaps more keenly aware of the significance of the win, as it also means New Zealand has won the event for the second year in a row.
Black Jack Jan Khan won the same title last year in Norfolk Island.
Beginning her campaign a week ago, Edwards rolled her way through the world's best female bowlers, only losing two matches in the entire event (to Hong Kong and Singapore), and into a semi-final battle with elite Guernsey bowler Alison Merrien - the same opponent she defeated in the World Cup.
Merrien proved to be a difficult challenge, but one that Edwards was more than ready to meet.
She defeated Guernsey 3-10, 8-7, 6-0, in Saturday's semi-final and then moved on confidently to address her Scottish rival in the finals; and once again prove that she really is the world's best female bowler.
