Amended Commentary – HY17 Interim Report

There is an error in the second paragraph of the Financial Commentary relating to Cash Flow at page 11 of the 2017 Interim Report. The paragraph reads: "The company elected to pre-pay some of its third provisional tax payment in March 2016, which would otherwise have been payable in July, to fully impute the 4 cents per share special dividend paid in September 2016." This paragraph should be replaced with the following: "The company elected to pre-pay some of its third provisional tax payment in March 2016, which would otherwise have been payable in July, to fully impute previously paid special dividends." The HY17 Financial Statements and the remainder of the HY17 Interim Report are unaffected. The attached Mercury HY17 Interim Report replaces the one released to NZX and ASX on the morning of 21 February 2017.
