Born in Milton, Mikaere-Wallis studied at the University of Otago before starting his career as a primary school teacher.
He then went on to be a lecturer at the University of Canterbury and then worked alongside neuroscience educators at the Brainwave Trust.
"It's really important to have someone like him visit Whanganui, especially as more children are coming through with issues around anxiety and need to build up resilience," Watson said.
"It gives you an awareness of the environments that some children are living in and how we just need to make school that safe, secure place where everything's a constant."
Watson had seen Mikaere-Wallis at a principals' conference in Palmerston North about two years ago and again when he visited Whanganui earlier this year.
She said some principals had donated money from an old lawn-mowing fund which allowed them to pay for the presentation.
"Everyone gave up that day in their school holidays so that they were in a better position to help the kids and I think that speaks volumes.
"I would love to see it as an annual event that we all put in our calendars and just know that every year is going to start with a high-powered professional learning and development day."
