Coronavirus-driven sharemarket volatility has delayed a massive merger involving Tasmania's biggest superannuation fund.
Tasplan in November announced a plan to merge with MTAA Super, which had primarily served the motor trades and related industries, although it was open to all.
At the time - well before the recent market crash - the two funds had an estimated 538,000 members and $35.8 billion in funds under management.
The merger was scheduled for October 1.
The funds announced on Thursday they had extended the timeline to not before March 31 next year because of the global coronavirus crisis.
They said sustained market volatility and concerns about the supply of specialist services were the key factors behind the decision.
MTAA Super chief executive Leeanne Turner said the reasons for the merger and the benefits to members remained unchanged and the funds remained committed to it.
"We still believe the merger is in the best interest of members of both funds," she said.
"A combined fund will provide greater efficiencies, improved products and services, increased capability, and better value to members.
So, we remain fully committed to the merger - just with an extended time."
Ms Turner said restrictions because of the virus had put extra strain on people.
"Clearly things have changed rapidly for all Australians in the last few weeks`" she said.
."We recognise the pressure that this is putting on our members and our staff, both at work and at home.
"We think extending the merger timeline will ease stress and help our staff better manage workloads and their personal arrangements."
Tasplan chief executive Wayne Davy said members were understandably concerned about their retirement savings.
" ... we'll likely see an increase in the number of people facing financial difficulties in the coming weeks and months," he said.
"By extending our merger timeline we can focus on getting members the service, advice and support they need right now.
"That's always been a priority for us, but now it's more important than ever."
Tasplan chair Naomi Edwards last year said the merger was expected to lead to a "considerable increase" of the fund's existing 150 staff in Tasmania.
