The number of people leaving permanently for Australia edged up again last month.
Statistics New Zealand reports 800 more people left for Australia than arrived in September, up from a net loss of 700 in August.
Overall, 1100 more people came into the country than left on a permanent basis in September.
That compares to net migration of 900 in July and August.
Migration to New Zealand has rebounded in recent months after dropping to a low of just 200 in June this year.
