New Zealand's World Cup preparations were rekindled when they beat Australia 23-10 in Pacific Four Series.
New Zealand's home World Cup hopes were restored by a new-look side with seven debutants.
Canada beat the United States by 36-5 in the Pacific Four opening match.
New Zealand had not played Tests for two years due the coronavirus pandemic. The defeats in 2021 and the loss against Australia combined made it their first win since 2019.
This is the first win for the side since Wayne Smith and Graham Henry, the men's World Cup-winning coaching duo, were appointed to the women's coaching team.
New Zealand will host the Pacific Four Series. On Sunday, the United States will face Australia (01:15 BST), while Canada faces the Black Ferns (3:45 BST).
Australia and New Zealand will compete in Pool A of the 2021 World Cup, which began in October and ends in February.
Australia has never lost to the Black Ferns, who won five of the six previous World Cups.
