Orokonui Ecosanctuary ranger Geoff Clarke inspects a a kiwi chick at the Orokonui Ecosanctuary recently.
Eight chicks were checked and all were in good condition, ecosanctuary conservation manager Elton Smith said.
"The fact that they have all put on good weight is a strong indicator that Orokonui is a great creche providing excellent habitat and husbandry,'' he said.
Staff had spent about 1400 hours caring for the chicks during the past year and volunteers had spent thousands more, he said.
The ecosanctuary expected to receive another three chicks next month, which would bring the creche total to 12, just two under its capacity.
