"I do a lot of running at school and I've competed in the school cross country every year. I joined the North Harbour Bays Club in the North Shore and I've been involved in athletics for about 18 months."
Sienna says she finds the Colgate Games interesting.
"It's really cool that people come from different areas of the country to compete and represent their clubs."
She says she has met many people through the Colgate Games.
"I love meeting other girls from different parts of New Zealand. On the first day I competed in the high jump and the Grade 10 800m run where I made the finals."
She says she was excited to make the finals.
"I came third overall in the qualifiers and I achieved a personal best time. I ran the race in 2 minutes and 53 seconds. I'd never ran 800m in under three minutes before so it was really exciting."
