Former Prime Minister and sitting member for Ialibu Pangia, Peter O'Neill, cast his vote on Monday 11 July in Kauwo Village east Pangia, where he grew up.
He was accompanied by his predecessor Roy Yaki and Sir Nathaniel Poiya.
Although Ialibu Pangia electorate voted, Imbonggu, Kagua Erave, Nipa Kutubu and Mendi polling was deferred to today.
Southern Highlands Election officials say the late distribution and confusion in the list of polling officials was the cause of voting delays in most parts of the province. Polling went ahead as districts received their ballot papers. Security in the province remains on high alert.
