The ceremony conducted at Sir Kashim Ibrahim Government House, Kaduna was witnessed by members of the state Executive Council, government officials and traditional rulers.
Yero replaced Gov. Patrick Yakowa who died in a helicopter crash on Saturday in Bayelsa.
In his acceptance speech, the governor pledged to continue with the transformation agenda laid by his predecessor.
“I sincerely desire to build on the good foundation that my boss had laid,’’ he said, adding that he would ‘’secure, unite and develop the state’’.
He paid tribute to Yakowa for his outstanding contributions to the development of the state and humanity.
“ He invested so much on this and had started reaping the fruits of his labour.
“His wish was to consolidate and advance on the achievements so far made and hence, tagged Kaduna State’s 2013 budget as Budget of Consolidation and Advancement.’’
The governor commiserated with the family of the deceased and people in the state over the loss of “a humble and dedicated person”.
“ His humility, dedication to duty, fairness to all and a high sense of humour, endeared him to many, near and far, irrespective of religious, tribal or sectional inclinations, ‘’ he added.
