The Storm will take on the Panthers, Rabbitohs and Dragons in pool play.
"They are all strong teams with a lot of good top players. However we will give it a good crack. We are representing the Storm ... we want to be as competitive as possible."
Harris will have plenty of support from his former Tamatea club. His parents, Paul and Dale, were among a dozen supporters from the club who travelled north yesterday and more were expected to arrive today.
A 22-year-old Hastings Boys' High School product, Harris enjoyed a meteoric rise in his first NRL season last year. He missed just one match after debuting with a try in the Storm's World Club Challenge win against Leeds 12 months ago and made his international debut in April's test against the Kangaroos.
His father made international headlines last February when he made a last-minute 31-hour journey to get to Leeds to watch his son help the Storm beat Leeds 18-14.
Harris joined the Storm in 2009 and the next year was the Storm Under-20s "Young Gun," the equivalent of MVP. In 2010, he also won the Ngati Kahungunu Junior Sportsman of the Year award.
It was Harris who had to step aside when Sonny Bill Williams did a U-turn and made himself available for the Kiwis' World Cup squad last year. His parents then cancelled their flights to the UK-hosted World Cup.
A Storm victory in tomorrow's final, with their son playing a prominent role, would be the ideal form of consolation for them. It's fair to say if the Warriors missed out on a final berth and the Storm made the final Harris and co would be a popular choice for the bulk of New Zealand support.
Before a ball has even been kicked in anger, or a five-point try scored, the NRL has declared the event a raging success.
Yesterday you couldn't turn around in Auckland without being reminded about the sold-out Eden Park event. NRL chief executive Dave Smith said the bold rugby league incursion into rugby union heartland had been embraced wholeheartedly by the New Zealand public.
"It's amazing, it's outside our wildest expectation the way it has been received," Smith said.
"The city is absolutely on fire. There is a real energy behind the event.
"I don't think there is anyone in New Zealand who isn't aware rugby league has come to Auckland. The teams are here to win. It is a serious tournament."
With the Nines expected to pump around $5 million into the Auckland economy, Duco Events director David Higgins, the brains behind the event, said the NRL should be congratulated on taking a risk and making the concept work.
