Act Party leader David Seymour believes the Government's reopening plan will "basically kill" the Bay of Plenty's tourism industry.
During a visit to Tauranga on Thursday, Seymour criticised the Government, saying in his view it was not "managing and balancing risk" in its reopening plan.
But Tauranga-based Labour list MPJan Tinetti said the Government wanted to avoid flip-flopping between restrictions.
Seymour said he believed the three-stage border opening, announced by the government on November 24, was too slow and too gradual.
"A lot of the Bay of Plenty is a beautiful place to be – it's got a great climate, great beaches, people come here as tourists. And yet, we've basically kneecapped the tourism industry indefinitely."
"It might be easier for me to close and lay everyone off. But hey, the Government's already doing that with teachers and doctors and nurses."
Tourism Bay of Plenty general manager Oscar Nathan said the Government's clear dates for reopening was what the industry had been waiting for.
But, he still hoped there would be changes to the plan.
"There are clearly areas we would have preferred were not so rigid and deferred in terms of quarantine conditions and dates."
He said in his view the seven-day quarantine for tourists "does seem somewhat excessive", but remains a long way off.
"We are hopeful these dates and conditions may improve or shorten between now and then as the government has alluded to."
Amy Neale's business Kewpie Cruises would normally run seven days a week at this time of year, but is currently only running weekends.
She thought the Government's reopening plan could help.
"Yeah, I imagine it will (help her business), but you don't know. You've just gotta hope for the best."
"We all know the virus is here to stay, so there's nothing they (the government) can do about that.
Tinetti agreed tourism needed certainty but believed a quick reopening would cause the opposite.
"We don't want to be flip-flopping like we're seeing countries do overseas," she said.
"We want to give our businesses, including tourism, some certainty around what is happening going forward, and at the same time keeping our country safe.
She acknowledged the frustration some were feeling, but remained committed to "putting people, all our people, at the centre of what we're doing".
She said in her view the seven-day tourist isolation protected the health system.
"We are fighting and containing community cases in this country now. We're not about to start introducing new cases of transmission (from overseas)."
While many business owners advocated for a fast and soon reopening, she felt "just as many" favoured a cautious approach.
"They (tourism businesses) can see that the end of heavily restricted travel is in sight, and that's what they need – some assurance that that's coming."
