In a letter to around 90 different schemes, Guy Opperman said they must begin sharing scam data with the industry's voluntary group, the Pension Scams Industry Group (PSIG), to create a clearer picture of the scale of the issue.
Greater data sharing, used in parallel with the improved pension transfer rules in the Pension Schemes Act, will ensure savers are better protected from unscrupulous scammers.
Minister for Pensions Guy Opperman said:
"Today I am calling on all pension scheme trustees to support us in the fight against the callous criminals stealing savers' pension pots.
"While the measures contained in the Pension Schemes Act are a significant step forward, we need government, the individual and industry to tackle this together.
"Pension schemes have a professional, ethical and moral duty to try and prevent their members being ripped off, and better data-sharing is a vital first step."
Not all pension schemes currently share scam data with the PSIG.
This data is used to inform Project Bloom, a multi-agency taskforce which coordinates efforts to combat pension scams and fraud.
PSIG chair Margaret Snowdon said:
"PSIG currently has 51 organisations participating in its industry forum, where we share information on potential scams. This helps us to protect members, but also means we can benefit from each other's experience and spot trends early.
"However, we need more schemes to be a part of it - schemes wanting to join can do so directly or by asking their administrator to join our forum."
On January 27 Guy Opperman gave evidence to the Work and Pensions Select Committee's inquiry into pension scams.
Since the Minister's initial request for data sharing during this appearance, PSIG have been receiving a steady stream of new applications to join.
However, around 90 large schemes still do not data-share, weakening Project Bloom's ability to tackle scams.
