Votes at 15 out of the 45 polling stations in Lamu East sub-county are yet to be tallied owing to transport and security challenges.
There were difficulties in the ferrying of ballot boxes and papers to the constituency tallying centre on Faza Island.
Area returning officer Japheth Omara said the 15 centres are in Basuba and Kiunga, where al Shabaab militants have carried out many terror attacks.
Omara said the challenges in these areas saw a chopper dispatched to transport IEBC staff and election materials.
“We have managed to count votes at 30 polling stations. We would have completed the exercise but our staff in Basuba and Kiunga couldn’t travel at night due to the unpredictable security situation,” he said on Friday.
“A chopper will ferry them this morning. We expect tallying in the entire constituency to end this morning.”
Results at the constituency tallying centre at Lamu West Arid Zone Primary School were announced as they streamed in.
Lamu West has the highest number of registered voters – more than 50,000 of the 69,776 voters in the county.
During the repeat poll on Thursday, Lamu Island and the general Lamu East witnessed low turnout but the numbers were higher in Mpeketoni which is considered a Jubilee Party stronghold.
Many voters across Kenya boycotted the election after instruction by NASA chief Raila Odinga, who withdrew from the race that would have been a hot contest with President Uhuru Kenyatta.
