Secondary school principals have accepted pay rises averaging 5% over two years.
The increases are nearly twice as large as those won by primary principals last year.
They are tagged to experience, with pay rising $3500 after three years' service, $7000 after six years and $10,500 after nine.
However, principals get that money only if they meet professional standards.
The structure means the increases will not be offered to primary principals, who last year agreed to a 2.75% pay rise over two years.
The PPTA and the Secondary Principals Association say the increases are worth between 3.75% and 6.7%, depending on experience.
Education Minister Anne Tolley has welcomed ratification of the deal and urged secondary teachers to settle their collective agreement.
