Goss was proud of her team's "fight" and indeed they had to show their character more than once during the event. France, on day one, and England in the Cup quarter-final asked questions, especially physically, of New Zealand. In the main, they responded well.
Canada were up in their faces in the decider and some of the passing was, as a result, shoddy.
Standout performers over the weekend were Goss and Ruby Tui for their high work-rates, Woodman for her potent finishing and Williams for her bruising defence and clinical finishing.
Australia took the bronze medal, edging Fiji 19-17, but, with no Cup wins in 2016-17, it has been some fall from grace for the 2016 Rio Olympic gold medallists.
The penultimate Women's World Series tournament takes place in Langford, Canada next month on May 27-28.
There is a suggestion, yet to be officially confirmed, that New Zealand's Black Ferns 15s players, such as Brazier and Woodman, will not be available as they will be gearing up for August's Women's Rugby World Cup in Ireland. The final sevens tournament will be in the French city of Clermont-Ferrand on June 24-25.
But in the meantime, the Black Ferns Sevens have the form on the board and the points in the bank.
New Zealand 17 (Niall Williams, Portia Woodman, Michaela Blyde tries; Tyla Nathan-Wong con)
Canada 14 (Hannah Darling, Jen Kish tries; Ghislaine Landry 2 con)
HT: 7-7
