Kiwi primary school teachers on Friday rejected pay rises of between 11 and 14 percent over three years, raising the possibility of further strike action.
New Zealand Educational Institute/Te Riu Roa members had voted to reject the deal, said the trade union in an email to teachers.
Te Riu Roa said it was now discussing the next steps with its members. Thousands of primary and secondary school teachers have taken part in waves of strikes since earlier this year, disrupting a sector already strained by serious staffing shortages.
"The negotiation team will inform the Ministry of Education that we want to resume negotiations. However, your negotiation team's view is that further action will be needed to pressure the Government to improve the offer," Te Riu Roa said.
"A survey is open now for teachers to give direction on what action we will take together.
"In a survey following the March strike, teachers favoured a further full-day strike if there wasn't an acceptable offer. The survey is a chance for you to tell us whether your opinions have changed."
Education Minister Jan Tinetti, a former school principal who took the portfolio earlier this year, has made improving pay and conditions for teachers a priority.
Other high-profile pay and conditions disputes in New Zealand that have caused disruptive strikes - including those involving secondary school teachers and nurses - remained ongoing.
