The Government's changes to migration rules will be challenged at a public meeting in Auckland on Monday.
Immigration Minister Michael Woodhouse last month introduced changes to the country's skilled migration eligibility criteria to attract more highly paid and highly skilled migrants.
Opposition parties argued the changes amounted to mere tinkering.
Unite Union, the Migrant Workers Association, Global Peace and Justice Auckland have organised a public meeting at the Unitarian Church in Grey Lynn on Monday evening.
They say the changes are creating a great deal of misery for many workers and students from overseas who have arrived under different rules and have had their hopes and dreams for the future dashed.
Industries employing migrant workers will be damaged by the changes and this will have a negative impact on the economy.
The Unitarian Church previously provided sanctuary for Indian students facing deportation after being duped by dodgy immigration agents.
The Government has created an exemption for the mostly dairy farm workers in the South Island to access permanent residence.
"We believe that there needs to be consideration given to extending this amnesty far more broadly," organisers of the meeting say.
