"It struck a cord as every child does deserve the best so we thought of ways we could use the slogan to start the conversation with parents and altered it to 'my child is worth it'."
The children started painting and writing "heartfelt" messages about their education and as their parents came in to kindergarten they joined in.
"It was great as the parents got involved with the messy art, putting their handprints on the posters showing their support for their children."
Ms Cullen said they flipped the slogan again to "you're worth it" asking the children what they wanted out of their education.
"If a small community like Bayview can do it then imagine the voice we could get from the whole country.
"It is about combining voices and getting more people to sign up. We need the momentum to continue."
Ms Oakly said since 2010 new government spending on early childhood education had gone solely towards paying for increased enrolments.
"Despite all we know about how crucial it is for children to have high quality early childhood education, the Government has frozen per child funding, cut funding for services that employ only fully qualified teachers, and increased the group sizes in early childhood education."
The pledge commits MPs in election year to ensure every child can get the best early childhood education possible by restoring the funding that has been cut during the past six years, reducing teacher to child ratios and group sizes and restoring the goal of 100 per cent trained teachers in early childcare education.
"All the evidence shows that early childhood education has a powerful, positive impact on a child's entire life but only if it is of a really high quality," Ms Oakly said.
She said while some children were getting a fantastic early childhood education others weren't and NZEI believe every child is worth it.
"We're asking MPs to sign the Have a Heart Pledge, and let New Zealanders know this election year if they are committed to giving our littlest children the best education possible."
