Jayden and Nathan said their favourite thing about school was the swimming pool, with the playground rating a close second.
They were not fazed about cycling to the bus stop then catching a bus to Okaihau for the first time on Thursday. In fact, it was Nathan's idea- their mum needed some persuading.
Ms Adams was "gutted" when she and the twins' father left the school on Wednesday.
"We were in the classroom for maybe 10 minutes," Ms Adams said. "They were quite happy for us to go."
The twins were the last of her five children to go school, which made it tougher, she said.
Like many mums, Ms Adams had looked after them full-time since they were born, so she said it was going to be a huge adjustment.
Picking the right first school for your child's needs was really important, Ms Adams said.
"I think, with the twins, I really investigated what school was going to suit them," she said.
"I really wanted them to be in a school that was small enough for them."
