- Former minister Amos Kimunya got 30,663 votes to win the Kipipiri parliamentary post.
The elections manager of Nyandarua County has postponed announcement of final results to Friday.
Mr Gideon Balang said his officers are fatigued and he could not overwork them past 6pm.
"I cannot overwork my staff. These people have been here since day one. They also need some rest," he said.
By around 5pm Thursday, Mr Balang was not sure of receiving results from three constituencies - Kinangop, Kipipiri and Ol Kalou.
He appealed to voters and candidates to be patient, assuring them nothing fishy was going on.
"I appreciate the patience exhibited by the candidates. I appeal to them to allow us some more time. It is a very tedious exercise, which must be conducted to perfection," Mr Balang said.
