"Two would be nice," the 22 year-old university student said this week, during a flying visit home to South Canterbury.
Rooney will compete individually and will also pair up with Nadine Stanton, of Te Kauwhata, a former Commonwealth Games gold medallist and Olympian.
While Rooney leaves for India on September 28, she has had little time to get excited about representing New Zealand at her first Commonwealth Games.
"I've got too much uni work to think about it yet.
I'm getting excited but I'm also getting a little nervous knowing everything I have to do to get ready for it."
Rooney's father Gary and brothers Sam, Cameron and William were all keen shooters.
After watching them compete, she decided to give it a go about seven years ago.
Being selected for the Youth Olympics in Sydney in 2007 was the beginning of her trench shooting, having previously only concentrated on down-the-line.
In 2008, she competed in a World Cup event in Beijing, her first major trench competition.
That year, she also went to Ireland for the world down-the-line championships where she won the individual women's title and was part of the winning team, and she also competed in the world university games in Beijing.
This year, she has been to the world down-the-line championships in South Africa where her team won and she was third in the individual event.
At the world International Shooting Sport Federation (trench) championships in Germany, she was 23rd out of 72 and was the top performing Commonwealth woman.
Rooney, who is studying accounting at Canterbury University, said it was a challenge juggling study with training and competitions.
While she was looking forward to the opening ceremony, she will miss the closing ceremony as she is returning to New Zealand for university commitments.
She is very grateful for the support of her parents, Gary and Adrienne, who are both heading to India.
