The teacher shortage that caused staffing issues in the mid-2000s seems to have eased - but the sector is warning that things could change very quickly if the economy improves.
A survey released this week found 172 schools started this year with nearly 200 teaching vacancies.
While that figure is slightly higher than in 2010, it's much lower than in previous years and down from a high of 424 vacancies in 318 schools in 2004.
The Ministry of Education's monitoring teacher supply survey found the vacancies at the start of the year represented just 0.5 per cent of all full-time teaching positions and that the overall drop during the past few years may reflect the continuing impact of the recession.
It said the supply of teachers was dependent on a number of things, including the recruitment of first-year teachers and overseas trained teachers and the overall trend since 2004 suggested the number of first-year teachers being employed was decreasing as the market tightened up.
