Voters in Kangema constituency braved a chilly morning to cast votes for their favourite candidate in a by-election that will give them a new MP for the first time in 24 years.
The seat was held by the late Environment Minister John Michuki since the 80s.
There was a good turnout as voters opted to cast their ballots early in the morning before embarking on other tasks.
Voters began trooping into polling centres from as early as 5am ready to choose an MP who will represent them for only six months before the March 4, 2013 general election.
The IEBC cleared six candidates in the polls.
Voters who spoke to Capital FM News expressed confidence in the ongoing process.
"I have come here so early because I want to send my candidate to work as I go to work," said one voter.
"I have voted for someone who will address some of the issues that are of concern to us such us the bad roads, lack of water, electricity, education and the issue of our farm produce," another voter said.
Independent Electoral and Boundaries Commission Returning Officer Benson Njau attributed the high turnout to the voter education that they conducted at the ward level.
John Gathogo of Mkenya Solidarity Party cast his vote at 8.30am at the Muguru Primary School Polling Centre.
Samuel Mwangi of Mzalendo Saba Saba was expected to cast his vote at the same centre later in the day.
Simon Mwangi of United Democratic Forum cast his vote at Nyakahura Primary School, while The National Alliance's Tirus Ngahu will be voting at Tutho Primary School as PNU's Paul Kimani Mugo votes at Kihoya Polling Centre.
