Area schools have joined in next week's mega-strike, which will now take out teachers at all state and integrated schools for the first time.
About 2300 teachers at the country's 136 area schools, who have their own collective agreement, have voted overwhelmingly to join the strike planned by about 50,000 primary and secondary teachers next Wednesday, May 29.
A Post Primary Teachers' Association (PPTA) spokeswoman said there had been no progress on setting up last-minute talks despite a PPTA offer for face-to-face talks and a Ministry of Education bid for talks facilitated by the Employment Relations Authority.
"We are full steam ahead planning for Wednesday," she said.
The strike will now involve teachers at all NZ schools except for private, non-integrated schools which have a separate union.
