"One of our girls grabbed it after the game and the team wrapped me up in it on the team bus after the game," Brazier said.
Brazier (20) packed the banner and brought it back to Dunedin with her on Wednesday.
Brazier and fellow Otago player Carla Hohepa were the star players of the tournament that the Black Ferns won for the fourth time when they beat England 13-10 in the final.
Brazier scored 48 points, the most at the tournament. This included eight points in the final.
Hohepa, the strong running wing, scored a try in the final and finished with seven for the tournament and was named the Personality of the World Cup.
"It was hard to describe but it was a pretty amazing feeling when we won," Brazier said.
"I was a bit worried when the score was 10-all but I never really doubted that we would win because we had the majority of ball."
Brazier kicked the winning penalty goal 15 minutes from the end.
"It was a tight final and all the games were physical," Brazier said. "Australia finished seventh at the World Cup last time and was third this year. All the teams had improved heaps."
Brazier was fullback against Wales but played second five-eighth in the other games.
"I'd never played there before. It is a much more physical game."
At the end of the game, Brazier and Hohepa were congratulated by Alhambra-Union clubmate Wahari Waitohi, who wore club colours to the game.
He was one of the Black Ferns friends in the crowd that watched the game.
Brazier was supported by 10 family members.
This included her parents, Gwen and Peter, and grandparents Albert and Joyce Brazier, who live in London.
"It was only the second time I'd met them," Brazier said.
A New Zealand-based cousin, Amy Stevens, was also at the ground and was joined by her mother's cousins from Scotland.
Brazier and Hohepa toured France and the Netherlands together after the World Cup before the winger left for Japan to join her boyfriend, former Otago representative Karne Hesketh, who is playing club rugby in Japan.
"I then joined some of the other girls in the team for the Beer Festival in Munich," Brazier said.
Brazier has completed her diploma in sports coaching at the Otago Polytechnic and will complete her personal trainer course next month. She hopes to enrol for a new sports science degree at the Polytechnic next year.
Over the summer months, Brazier intends playing sevens and touch.
Her next major international focus is the Sevens World Cup in 2013, and the next Rugby World Cup in 2014.
A longer term goal is to make the New Zealand Sevens team for the Olympic Games, at Rio de Janeiro in 2016.
