He urged the principals engage with recruitment companies early.
"When you know there's a vacancy at your school, please get in touch with them. Ask how they can help, ask them about the candidates they are getting, tell them the type of person you want," Hipkins said.
The Government announced earlier this month it was ramping up efforts to attract more than the 850 teachers estimated to be needed in primary and secondary education, with an extra $10.5 million in funding, grants of $10,000 for schools to get more graduate teachers into classrooms and $5m more for overseas relocation grants and finder's fees.
