Moving to Mercer Business Super


As part of our ongoing commitment to make managing super easier for you and your clients, we’re moving all Mercer Super plans to a single, modern technology platform.

Around 20 March 2026 your clients with a Mercer Super Trust – SmartSuper plan or Mercer SmartSuper Plan will be transferred to Mercer Business Super.

The move will make it easier for you and your clients to find key account information like Unique Superannuation Identifiers (USIs).

To ensure all member accounts are transferred safely and accurately, there will be a Limited Service Period from 4pm (AEDT) Wednesday 18 March to 9am (AEDT) Tuesday 31 March 2026. During this time, some transactions will be unable to be processed.

Here are some actions you can take to help support your clients through the transfer and beyond.
