The head of the under-pressure Electoral Commission has apologised once again, for yet another voting day error.

Earlier this week, the Herald revealed 3 voting places where the data entry was incorrect.

But after an investigation, the Commission revealed that number was actually 15.

Chief Electoral Officer Karl Le Quesne says this was a regrettable error.

"It appears the quality assurance checks didn't pick it up- they should have. When we went through yesterday and applied all those checks again, that's when we found things didn't reconcile."

Overall results have not been affected, nor the electorates where recounts are underway.
