Omnis funds are available only to advisers in the Openwork network.
The six new funds include a UK All Companies fund, which will be managed by Colin Morton and colleagues at Franklin Templeton.
Mr Morton won the right to manage an existing UK mandate for Omnis earlier this month.
Darius McDermott, managing director at Chelsea Financial Services, described Mr Morton as a manager with a "solid track record."
A UK smaller companies fund is also being launched, and will be run by Richard Bullas at Franklin Templeton.
Omnis is also to launch an Asia Pacific excluding Japan fund to be run by Veritas Asset Management’s Ezra Sun.
A new Japanese equity strategy will be managed by Andrew Rose and Masaki Taketsume of Schroders.
Columbia Threadneedle Investments will manage two new fixed income strategies, a UK gilt strategy headed by Dave Chappell, and a sterling corporate bond strategy run by Alasdair Ross.
A representative of Omnis said the changes will be make it easier for Openwork clients to understand how their money is being managed, and added it is likely there will be further fund launches in 2019.
All of the new product launches are subject to standard FCA approval.
