Tens of thousands of eyes will be on 6-year-old Hannah Underwood tonight - but she isn't nervous.
The Red Beach School pupil will have the important task of switching on the lights of the 21m-high solar-powered tree at Coca-Cola Christmas in the Park at the Auckland Domain.
The tree, which took 10 people and a crane seven hours to decorate, is powered by 20sq m of solar panels.
It also includes a battery storage system which allows power to be saved for when night falls.
Hannah's only experience in front of a crowd so far was earlier this year at a school production, when she performed for about 100 parents.
"I feel really special about my job of switching on the lights.
"And I am also really excited about meeting Stan Walker," the little girl said.
Mother Karen entered Hannah after seeing the competition for children aged 6 to 12 - run by power company Vector - advertised online.
Ms Underwood said Hannah was "ecstatic" when she found out she had won.
"She was like, 'Oh my god', screaming and yelling.
"She's a very confident girl, she likes to do that kind of thing, so to do it on such a large scale is really exciting."
Hannah, who lives in Stanmore Bay on the Whangaparaoa Peninsula, is so confident she has even told her mother to keep clear of her while she's on stage.
"I said to her I would be right there if she wanted me, and she said, 'I don't want you on stage with me'," Ms Underwood said.
"She just wants to be out there on her own."
