In his view, "no one has any confidence going forwards" because of the changing Covid restrictions and regional lockdowns.
"The Government is flipping daily on restrictions. When you shut Auckland and Hamilton, everything is affected."
Berryman also shut the doors of his jet boat tourism operation - Riverjet - for at least 18 months in March after losing 85 per cent of international visitors because of border closures.
He told the Bay of Plenty Times the pair would "love to open" again when there was a "flow of international visitors".
"Until then it is unsustainable."
The pair were now looking forward to being semi-retired and having "some adventures and a bit more personal time".
But he said semi-retirement had been "bought on prematurely by Covid".
"We are another casualty - it is clear and simple".
Highlights of their 12 years of owning the lodge included meeting people, hosting "amazing events" and having the lake all to themselves, he said.
Some guests had been returning to the lodge for about 40 years with many "repeat customers".
They had also hosted "hundreds of weddings" while owning the lodge and had generations of families come through its doors.
"We have made a lot of very close friends through the lodge."
Berryman still fondly remembers hosting the BMW Motorrad in February 2020, when 200 people from 23 countries stayed at the lodge.
The Berrymans would host their "last wedding ever" on January 3.
"Nothing is forever. Things just change and take their natural course. It is sad for us to be leaving here but it is one chapter of our book closed," he said.
Owners of a Tauranga wedding venue also made the "difficult decision" to close in September after being "hit hard" by Covid-19 restrictions.
Waimarino Group director Blair Anderson previously said Waverley on Wairoa had been "haemorrhaging" since the first round of Covid-19 lockdowns last year.
"The funds are drying up. So we are having to make a hard call, and now it just becomes like downtown Tauranga - empty buildings," he said.
The function centre based at Waimarino Water and Adventure Park closed at the end of November.
The Wairoa riverside venue, which could hold about 150 people, was unable to operate with alert level 2 restrictions in place.
"Numbers have dwindled right down. Covid-19 has taken a toll on another business, another livelihood, as well as the mental stress that goes along with it."
The Department of the Prime Minister and Cabinet was approached for comment.
