(Reuters) – Australia’s competition regulator said on Monday it has delayed its decision on ANZ Group Holdings’ proposed A$4.9 billion ($3.30 billion) acquisition of Suncorp Bank by a week to Aug. 4, and has requested a week’s extension.

The Australian Competition and Consumer Commission (ACCC) requested an extension until August 11 in a letter to ANZ on Thursday, saying it needed more time to review reports and materials longer than 50 pages.

“It is important that the ACCC has the opportunity to meaningfully consider the new information provided by ANZ and take this into account in making its decisions,” the regulator said.

“As a result, the ACCC believes that an extension of the two-week deadline is both necessary and appropriate, and we now seek confirmation from ANZ that it has agreed to that extension.”

The country’s fourth largest bank, ANZ, in its reply on Friday agreed an extension until August 4.

ANZ did not immediately respond to a Reuters request for comment.

This is the second time the regulator has sought an extension in its decision after the original mid-June deadline was extended till the end of July.
