"The benefit for the children is it's embedding understanding around the importance of clean waterways. And also, they're getting to do work of direct benefit in their local area, and they can see the plants growing over time," Linda said.
Frank said he was keen to protect waterways in the area and enhance the environment generally, and is grateful for the pupils' help.
"If you ask everyone they always want clean water. If you don't do it properly, dairying is going to have effect on water," said Frank, whose property has won awards in the Waikato section of the Ballance Farm Environment Awards.
Council catchment management officer Warren Coffey says farmers can apply for up to 35 per cent of the costs of fencing and planting to protect and enhance waterways and wetlands, as well as soil conservation work such as preventing steep hillside erosion.
"It's our way of supporting farmers to make changes on their property that help provide environmental benefits for the wider community."
Ruairi Kelly, the council's schools programmes coordinator, said the visits have enabled the Tauwhare children to learn about both the environment and farming.
"Tauwhare has done really well under Enviroschools - they're a high-ranking Green-Gold school.
"Enviroschools in the Waikato is supported by a team of facilitators who work with schools to engage on a long-term journey of learning and action over environmental issues. The work of Frank's farm has been a great partnership between a proactive and caring farmer, and a school that's been working really well on the environmental protection front."
