PNG's first prime minister bowed out of politics with the tag as the longest serving politician in the country, and also in the Commonwealth of Nations.
Sir Michael voted at the Wewak Hill polling booth in the Wewak Urban ward.
He casted his vote in front of Lady Veronica Somare, and East Sepik Regional candidates Dulciana Somare and Alan Bird.
This term of Parliament was Sir Michael's final term as a public servant.
Provincial Election Manager Kila Ralai confirmed that Wewak Urban will have two days of polling.
