Mr Goff pointed to his party's education policy as something all New Zealanders could relate to.
"I know John Key thinks that class sizes don't matter, but where did he send his kids - to a private school that advertises small class sizes and more individual attention," he said.
"We want to reduce class sizes, which is very important to a child's ability to learn.
"As a parent, we all want our kids to do really well.
"But, every kid that misses out and is unemployed, or who doesn't achieve their potential, is a cost to all of us.
"We are all in the same boat and we want everyone to do well, so we need to give them that chance."
New Zealand First supporter Alan Land has a soft spot for Mr Goff and was having lunch at the Citizens Club when the Labour MP arrived.
"I watched him on Back Benches last week.
"I don't know why they don't make him leader again," Mr Land said.
Mr Goff also met Rotorua Mayor and former Cabinet colleague Steve Chadwick, members of the Rotorua Newcomers Network and Multi Cultural Society, and members of the Rotorua RSA.
He finished his long day with an Indian ethnic feast at Gandhi Hall.
