Brazier (23) made her debut in sevens this year and played a key role in helping New Zealand win the inaugural women's world series.
''My long-term goal is to make the team to go to Olympic Games in Rio de Janeiro in 2016,'' she said.
''I always wanted to go to the Olympic Games but none of my sports were in it in the past. Now that sevens is in, it's pretty cool.''
She was selected in the New Zealand sevens team in 2009 but was forced to withdraw because of a knee injury.
Her immediate target is to help New Zealand win the world cup in Russia next week.
''I think I've been getting more nervous for the sevens than for the 15-a-side game,'' Brazier said.
''But as soon as I'm out there, it all goes.''
Four members of the sevens team have also been named in the Blacks Ferns squad to play England in a rare home series next month.
They are Brazier, Selica Winiata (Manawatu), Renee Wickcliffe (Counties-Manukau) and former Mystics netballer Portia Woodman (Auckland).
Brazier is the only Otago player in the New Zealand sevens team. But she has been joined in the Black Ferns squad by provincial team-mate Kathleen Wilton, a prop. Centre Claire Richardson, who played for Otago last year and is now living in Auckland, is also in the team.
''I'll play sevens to the world cup and will then focus on the 15s,'' Brazier said.
The New Zealand sevens squad is expected to get contracts with the New Zealand Rugby Union next month.
''It won't be fulltime but it will be semi-professional,'' Brazier said.
''Some of the girls are working fulltime and find it difficult to train twice a day. It will definitely help out.''
Brazier was a key member of the Black Ferns side that beat England to win the World Cup in 2010.
''It was surreal that we'd won. It was close and went down to the last couple of minutes. We won by three points,'' she recalled.
Brazier is enjoying the change to sevens.
''It is something different and gives me a lot more space to run. It is a growing sport.
''Physically, it hits the lungs a lot more in sevens. There is not as much contact. But Russia and Canada are more physical and take the ball into contact and we get sore after their games.''
The Black Ferns will defend their title at the world cup in Paris in August-September next year.
Brazier, a noted goal kicker in the 15-a-side game, is getting used to the drop kicks that are used in sevens.
She has only played three club games for Alhambra-Union this year because of her sevens commitments.
