Estella Lee is a newish New Zealander who fell in love with our country and decided to do her part for the environment.
When Lee went to one of our National Parks two decades ago, she had many questions about our environment.
But instead of keeping the answers to herself, she started passing on what she learnt.
Lee is the founder and head of the Chinese Conservation Education Trust.
She holds classes at the Waitakere Sustainable Living Centre, where her students sing her praises.
"She's an amazing woman," says one student.
Twenty years ago, Lee was like her students. She came to New Zealand for a new life but didn't know much about the land she was now living on.
"We know very little because we are all townies, in Hong Kong, if we don't litter then we are a very good citizen already. To recycle the garbage is not our business," says Lee.
So she learnt, and decided it would be a waste not to share it.
"I have the chance to learn and if I don't pass it on, I have wasted the gift god gave me," says Lee.
"We need to protect the environment, we have the passion for it and I like to learn and I like share it with my fellow people," she says.
"I think everybody's got to do something."
