The Prime Minister, John Key, says the Government is still committed to stopping the exodus of New Zealanders to Australia.
Statistics New Zealand says a net 39,100 people headed across the Tasman last month, a record high.
Mr Key says some specific issues, such as the Christchurch earthquakes, have led to more people moving to Australia.
He says the government's 120-point economic plan is expected to deliver more jobs and narrow the wage gap with Australia.
