Ian Greenwood has been appointed to lead the £46bn Northern Pool, which was set up by the local government pension funds for Greater Manchester, West Yorkshire and Merseyside.
Greenwood, who is deputy chairman of the West Yorkshire Pension Fund and deputy chairman of the Local Authority Pension Fund Forum, replaces councillor Kieran Quinn who passed away unexpectedly before Christmas.
The Northern Pool is one of the largest eight pooled vehicles, which were due to be up and running by the government's 1 April deadline.
A statement from the pool announcing his appointment said it is finalising plans to form an asset pool.
Greater Manchester Pension Fund chairwoman Brenda Warrington, who took on the role in January, said: "Ian's appointment is another important step in our pooling journey. I'm confident he will continue Kieran's good work, using investment to drive growth and innovating with our stakeholders to ensure sustainable and affordable pensions for workers who deliver vital public services in the interests of taxpayers."
Merseyside Pension Fund chairman Paul Doughty added that Greenwood's experience and knowledge of the LGPS would be "invaluable in ensuring continuity and in helping the Northern Pool achieve its objectives at this time of significant change."
PP has interviewed some of the pools as they made their final preparations to meet the deadline.
