However, it is understood employment-related legal action is being considered on Mr Leurquin's behalf.
He yesterday declined to comment on his departure or any possible legal action.
Mr Leurquin worked at the museum for about five years before leaving several months ago.
He had also been a conservator at the Otago Museum for eight years, until 1998.
Settlers museum director Linda Wigley said she could not comment on any suggested legal action.
A report within the agenda papers for today's Otago Settlers Museum Board meeting noted that Fiona McLaughlin, who is conservator at the Scott Polar Institute at Cambridge University, was the "successful candidate" for the museum conservator post.
Museum officials said Ms McLaughlin's starting date had yet to be finalised.
The report noted she had had a "wealth of museum and conservation experience", including nine months at Scott Base in the Antarctic, as well as time at the Royal Armouries and a UK-based heritage conservation practice.
Ms Wigley said interviews had also been undertaken and good progress made in making appointments to a new post of communications and business team leader, and for a research curator, the latter to operate for a fixed term during the museum's $35 million redevelopment project.
The communications and business team leader would not only help with communications, but would also have an important role in overseeing business activities in the redeveloped museum, and "a huge amount of site management", including the museum shop and a new cafe, she said.
The museum had also been seeking exhibition technicians.
Only some paperwork needed to be completed before some of the latest appointments were confirmed, she said.
William McKee has also been appointed as an "interpreter" during the redevelopment project, helping museum staff with several tasks, including developing exhibitions.
"We're building our own team," Ms Wigley said.
