On May 6, Sweetman said Milford condemned Henry's comments but was keeping its shares, for the time being, because owning a stake allowed it to get a foot in the door to discuss the issues.
Milford had sent a "please explain" letter to DGL.
Yesterday, she updated Plessis-Allan that Milford had a meeting with Henry and DGL chairman Peter Lowe last Wednesday.
"It was a difficult ... but very constructive meeting," Sweetman said.
"Difficult in that we shared with them some of our thoughts on the impact of those comments that he made. But constructive in that they were willing to listen to our views, and also take on board some of the feedback that we gave them about some of the changes we thought they needed to make."
She added, "We do think we played a big part in getting the ASX and the NZX releases out and also in getting that independent diversity review across DGL Group under way. So that was really positive from our perspective but no, we're no longer shareholders in the group."
There was no market disclosure of Milford's sale, indicating its stake was under 5 per cent.
The Australian chemicals company is 57 per cent owned by Henry, a New Zealander.
In a May 12 ASX and NZX filing, DGL said it planned to hire an independent adviser to carry out a diversity and culture review "and recommend any changes necessary to ensure the culture reflects key values".
The filing also said, "The Board has previously stated that the comments were offensive and unacceptable ... The remuneration framework for all DGL Group senior executives will be reviewed by the Board's Remuneration Committee, with a plan to implement a balanced scorecard approach for assessing at-risk remuneration, targeting an implementation date of 1 July 2022.
"Mr Henry understands the importance of his own conduct in setting standards across DGL Group. He is fully supportive of, and will participate in this process initiated by the board."
The controversy resulted in several investment and KiwiSaver firms, including Devon Funds and KiwiWealth, saying say they would shun DGL.
The company's shares, which were trading at $4.50 before Henry's comments about Lim were reported, fell sharply and were at $3.14 on May 14.
However, the stock has recovered some ground in recent days and closed Wednesday at $3.48.
