New pay offers have failed to stop secondary and area school teachers resuming industrial action and primary teachers could yet join them.
The Education Ministry made revised offers to all three groups of teachers following a one-week pause in action.
Some teachers told Checkpoint they will be voting against the offers, but others are not sure.
It means rolling strikes for different year levels are back on with some Year 12 students rostered off tomorrow and years 9 and 10 next week.
