In the interview, Detective Sue Mackle questioned Kennedy about his family history, particularly for the five years the complainant was in his and his ex-wife's care in Greytown.
The court was told the couple had three other daughters who were older than the complainant.
The complainant alleged she was never treated the same as the three other girls, including not being able to eat with the family at dinner time.
But Russell Kennedy said he did not recall that ever happening, nor did he recall his adopted daughter ever being treated differently to the other children.
"It was good. She played up, she always played up. You had to pay her a lot of attention all the time.
"She was just one of the kids."
Teachers at Greytown Primary contacted social services because the young girl was often turning up to school without lunch and would take food from the rubbish bin or steal it off other children, Ms Mackle said in the interview.
Russell Kennedy said she had the same lunch as every one else.
"When she was with us she would even go to the rubbish bin," he said.
The school was also concerned that the girl would turn up to school with welts on her legs.
When the complainant later went to police she said she was hit with jug cords and hockey sticks.
"I played hockey, but I never hit her with the stick," Russell Kennedy said.
"To us they [bruises and welts] were always there, she could walk around home and come in a bruise or welt."
The complainant also said Russell Kennedy once set one of the family dogs onto her but in the interview Kennedy denied the accusation.
He was also accused of holding her under water while bathing her, as well as throwing her into the local pool.
Kennedy told Ms Mackle that he did not recall ever doing that. He did recall throwing the girl into the pool to help teach her how to swim, but he said he would follow directly behind her.
The trial continues.
