The country will open to the world at the end of July with sector-specific settings to shift away from low-skilled migrant labour.
Minister Kris Faafoi says Immigration New Zealand has hired 230 more staff and moved the application system online in preparation.
Kris Faafoi says the new online system will mean people can track their application's progress online instead of ringing an 0800 number.
National says significant questions remain around how Immigration New Zealand will cope with the demand.
Party spokesperson on immigration Erica Stanford spoke to Susie Ferguson.
