Fifteen voting places have been found to have data entry errors causing changes for electorate candidate results.

The Electoral Commission has just released amended official results after doing a full check of party, electorate and special votes.

Errors include one electorate where some special votes were entered incorrectly, and 620 votes in the East Coast that were included in the preliminary count but not the official count.

ZB political editor Jason Walls says this mistake adds to a worsening look for the Electoral Commission.
