The primary school teachers union remains unconvinced by a proposed $360 million plan to create new roles for top teachers and principals.
The Government wants to pay 60000 educators more to work with groups of schools in an attempt to raise student achievement.
The New Zealand Educational Institute says it may still oppose the package.
National secretary Paul Goulter said a meeting on Tuesday night decided to request more details about the proposed new positions of executive principals and expert teachers.
He said the union expects the Government will seek to vary its members' collective agreements to allow for the introduction of those positions.
