"I had kids telling me their life stories. I had a girl paint a picture of her father in jail with these thick dark lines. I spent a lot of my time with kids that had real problems, children that had been locked away in small spaces for a long time," McGowan said.
"Some children would come, paint and then run off but others would come for three to four hours and just paint."
The two weeks had been emotionally draining and she was now exhausted but the trip had brought joy to her heart, she said.
McGowan said at one stage a group of children would stand together and sing the alphabet to her while she painted the walls.
"I don't think people really understand but just seeing the benefits in the children and the joy that painting gave them, makes it all worth it."
McGowan, who works at Mount Maunganui Public Library and drives the mobile library, took time off for the trip.
Orphanage director Pauline Curtis-Smith will hold an art auction of some of the children's artwork later this month in Tauranga to help raise money for the foundation. The auction will be held on August 18 at Farmer Autovillage, Hewletts Rd, Mount Maunganui from 2pm. Entry is by gold coin donation.
