THE STATE government will advertise for a "strengthened" children's commissioner at the end of the week.
Human Services Minister Jacquie Petrusma said a national search would begin on Saturday, and the job description would include more power.
Tasmanian children have been without a permanent advocate for more than nine months after former commissioner Aileen Ashford quit, criticising the role's lack of advocacy powers and its three-year term.
The state saw four commissioners and two acting commissioners leave the position in less than 10 years.
"We don't want to see future commissioners leaving the job and expressing frustrations about Tasmania and the role," Ms Petrusma said.
"That's why this time we need to make sure that we finally get the recruitment process for this very important position right for our kids' sake."
The government will implement the recommendation that the tenure be extended to five years, following an inquiry into the position.
The state opposition is calling on the government to explain why it has readvertised for the position.
Lyons MHA Rebecca White said Ms Petrusma needed to "explain what circumstances have led to a delay in the process".
"An independent panel made a recommendation for this position shortly before the election," Ms White said. Ms Petrusma said a candidate had not been selected before caretaker mode.
