Secondary school teachers are inspiring mass frustration over their plan to resume striking.

These teachers voted to reject the Government's latest collective agreement offers.

They're refusing to teach two levels each day, from Monday to Thursday over the next three weeks.

Finance Minister Grant Robertson says the Government's latest offer makes 'significant progress' for teachers, and the primary teachers agreed to a similar deal.

"Personally, I think an 11 percent average pay rise- and some teachers would get an 18 percent pay rise- plus a one-off payment of $5,000 for teachers represents, in the environment we're in, a really good offer."
