Leaver's trust is one of 12 winning charities in this year's Auckland Airport 12 days of Christmas project; now in its sixth year.
The trust will receive $10,000, which they will use to buy up to 200 pairs of sports shoes for children from a variety of primary and intermediate schools in Auckland.
Leaver acknowledged that sports shoes could be very expensive and for many families were considered a luxury item they just could not afford.
"That's why we started this whole thing. We want these kids to start walking the road - playing sport.
"A lot of them are embarrassed to come out to try-outs because they don't have shoes. This is their start."
Leaver said she was a prime example of someone who had struggled when she first started playing netball.
"I can tell you, a lot of professional athletes now had nothing - no shoes, gear and all that. This is just a way of making sure every child has a chance to make it."
Another unique feature of the trust is that it was connected with some of the country's top schools - whose students regularly donated pairs of shoes for fellow students from other schools.
Auckland Airport spokesman Charles Spillane said the charity was doing good things within the community.
"We're delighted that through this programme, we can help provide children with the opportunity to get involved in sport - something that every New Zealander should have the chance to do."
