"Please feel free to join our concerns and email our Immigration Minister."
Co-owner Robert Heeps said five of his 25 staff had resigned since the announcement of the proposed changes.
"They want to move to Hamilton, Tauranga or whatever, to try to pick up extra points to get through their immigration applications before the rules change," Heeps said.
Co-owner Olaf Blanke said he had trouble recruiting because many were now re-considering their career in hospitality, and the rules also made it difficult for him to employ staff with the skills he needs.
"We shortened our hours because we just can't get the staff," Blanke said.
"We just want the Immigration Minister to scrap the changes, and ask our customers to do the same."
Restaurant Association chief executive Marisa Bidois said many in the industry are nervous and anxious about the proposed changes.
"Generally speaking the industry has been struggling with a skills shortage for over 10 years and adjustments to the status quo will impact our industry negatively," she said.
"Many restaurant workers are now making decisions based on what they think will happen."
Association members met Immigration NZ yesterday, and many expressed unhappiness with many aspects of the policy changes.
Immigration policy director Shane Kinley said the agency had so far received more than 60 written submissions.
These included individuals and organisations in the construction, education, dairy, restaurant and care sectors.
"Meetings have been held with industry bodies representing retail, health, construction, tourism, hospitality, transport, dairy and primary industry sectors, and also with the Small Business Development Group, BusinessNZ and the Council of Trade Unions," Kinley said.
"The meetings have been effective in raising awareness of the consultation and identifying issues that are likely to be raised in submissions."
Kinley said no comment will be made on the feedback until the submissions have been analysed and considered by the Minister of Immigration and final decisions made by Cabinet.
