Jubilee party and ODM candidates cast their vote at dawn as the polls got underway.
Mr Maxwell Magoma (Jubilee) and Naftali Onkoba(ODM) sounded optimism of emerging winners.
There were, however, a few hitches as the exercise kicked off on Wednesday morning.
At Sugubo and Isena polling stations, BVR machines broke down temporarily affecting the exercise.
A man was also injured on Tuesday evening over alleged voter bribery. Police have however not confirmed the incident.
Mr Onkoba of the ODM claimed that there had been incidents of voter buying by rival parties.
"We condemn it in the strongest terms but we have instructed our agents to be vigilant," Onkoba told the press.
Ward returning officer Ms Jackline Osiemo said complaints on malpractices by the candidates will be filed formally with the commission for probing.
"We anticipate the exercise to be free and fair. The casting of votes has already begun well and no ugly incident has been reported so far," she said.
There were evidence of voter apathy in some polling stations as voting begun.
At Sugubo for instance where the ODM candidate casted his vote, only a handful voters turned up.
Mr Fred Ogeda, a voter at Keera polling station said the exercise was going on well.
Kenya National Congress candidate Mr Caleb Ong'uti who also cast his vote at 8 am at Keera polling station also claimed massive voter bribery by rival parties.
He singled Chitago polling station where he accused ODM officials of bribing voters with Sh500 each even as campaigns closed on Monday.
