The corporate member of the Institute of Financial Planning found platform ETF assets under management grew by 52 per cent between December 2010 and December 2012.
Particularly strong results came from corporate bonds and developed market equities.
The firm said the growth was due to advisers becoming more confident in the ease and cost-effectiveness of using ETFs.
In the first quarter, corporate bonds had the highest inflows but governments bonds performed best in the second quarter.

Developed market equities and corporate bonds both saw inflows in the third quarter but property ETFs reported outflows.
Property continued to see outflows in the fourth quarter, as did government bonds while developed market equities, emerging market sovereign bonds and dividend-focused ETFs saw inflows. UK equities saw £22m in inflows while £27m came via five euro equity ETFs.
Pollyanna Harper, head of intermediary sales at iShares, said: "Advisers and investors are adjusting to this new world of increased market volatility, low yields and the RDR enforced changes to adviser pricing.
"The leap in iShares platform ETF assets under management and last years flows suggest the retail investment market is becoming more aware of the convenience and cost effectiveness that ETFs provide and are becoming more confident in using them."
