The bank released millions of shares in a capital-raising in 2015 that fell short of the $2.5 billion anticipated from the venture.
Its underwriters then stepped in and bought between $754 million and $790 million worth of shares, which was not disclosed to the ASX.
The Federal Court in October found the bank guilty of breaching disclosure laws.
Justice Mark Moshinsky today ordered ANZ to pay a $900,000 penalty for its failure to alert the market and investors of how it gained the funds it raised.
When he handed down his reasons, he said the fine was needed to deter similar actions.
ANZ was also ordered to pay the legal fees of the Australian Securities and Investment Commission, which sought legal action against the financial institution.
This was a “landmark case”, the commission’s deputy chair Karen Chester said.

“Today’s decision confirms the paramount importance of continuous disclosure,” she said in a statement.
“The penalty and remarks from the Judge today are a clear and resolute message to ANZ and the market that this conduct was very serious.”
Chester said continuous disclosure was “key” in maintaining market integrity so that investors could make informed decisions.
In 2015, the bank issued a release announcing it had raised $2.5 billion in new capital through the sale of approximately 80.8 million shares at $30.95 each.
It is understood ANZ was aware its underwriters had allocated almost $800 million of those shares to themselves at the time.
At the time of the judgement, an ANZ spokesperson said the bank acknowledged the decision and that it was reviewing the finding.
ANZ has been contacted for comment on the penalty.
