Low-income families with children will be able to almost double their weekly tax credits if they move to Australia by 2018, an analysis has found.
In a pre-election "state of our children" report, the Child Poverty Action Group says this year's Budget cuts in Working for Families tax credits will create a dire "Tasman gap" between family support in the two countries by 2018 when they will be fully phased in.
Auckland University economist Susan St John said the cuts were subtle and would take effect slowly until 2018.
"They don't appear to hurt much, but over the time the differences between us and Australia will become ever starker," she said.
Families on benefits can already roughly double their tax credits by crossing the Tasman, from $88 a week to A$170 ($217) for a one-child family. That relative gap will be unchanged in 2018, assuming that family support is adjusted for inflation in both countries.
