The 3-year-old was put in a clothes dryer spinning for 30 minutes on a hot setting, hung on a clothesline and spun around, held over a burning fire, used to practise wrestling moves, folded into a couch and sat upon, shoved into piles of rubbish and cold baths, dragged half naked through a sandpit, thrown at walls and dropped from heights, and had various objects hurled at her.
The Herald revealed earlier this month that Kemp was back before the courts.
For legal reasons she could not be named.
But on Friday she admitted charges of assault, theft and breaching intensive supervision conditions.
A charge of disorder was withdrawn.
It is understood the assault occurred on Karangahape Rd in central Auckland soon after Kemp was caught stealing a bottle of Coca-Cola and can of Pringles chips.
