The group Grounded Kiwis goes to the High Court today to press its case against the MIQ system.
They are seeking a judicial review of the system that has seen many thousands of New Zealanders abroad unable to secure a place in the lottery system and therefore unable to return home.
Grounded Kiwis says this is unlawful, unreasonable and breaches the Bill of Rights.
The case is expected to last two days.
Grounded Kiwis' spokesperson Martin Newell spoke to Susie Ferguson.
