The x-ray confirmed that the chick was in the wrong position for it to be able to hatch by itself. Despite assistance from staff, it did not survive.
"Having the x-ray available meant that we could confirm our suspicions quickly and easily, and make an attempt to assist it to hatch," said general manager Helen Tickner.
"However, this little kiwi chick had a number of problems, which meant it would never have survived outside of the shell and, sadly, we haven't had the outcome we would have hoped for.
"But a big thank you to South Wairarapa Vets for their mercy dash at such short notice."
Dr Evans said it was the first time he had x-rayed a kiwi egg.
"Usually these machines are used in our equine division.
"But it was great to be able to help out the team at Pukaha and we're really pleased that we could be of assistance," he said.
