She was a product of the captive kiwi breeding programme, which husbandry manager Claire Travers said played an integral role in the preservation of the native species.
"Captive breeding is very important as an insurance policy for wild birds and the captive population is managed by a national co-ordinator who matches up suitable kiwi for breeding around the country."
Ms Travers said it had been an exciting week for Forest.
"Forest is a real favourite with staff and park visitors because of her placid nature and huge appetite. She's infamous for scoffing her food - she has to have limited amounts so she doesn't get out of shape."
Forest was the 12th chick to hatch from the captive breeding pair, Tahi and Bracken.
Rainbow Springs recently hatched its 81st egg.
