Students will have many units to complete with a local focus, including looking at the processes and production involved in making honey.
"A lot of the local families, their jobs and livelihoods depend on the environment," Ms Dallas said.
"Through beekeeping and through the farming that they do - becoming aware of the environment is very important for our students here."
Ms Dallas was born in Whanganui and when she began at Ngamatapouri School it was her first time back in the region for 33 years.
During eight of those years, Ms Dallas lived in Brunei, Borneo, where she was a teacher and also an education manager.
"I've had a lovely term and am really looking forward to being here on a permanent basis," she said.
"This was a lovely opportunity to get back to rural life, being with a very supportive community and a small group of learners who are a lovely bunch of kids."
