Noah Hukatai-Pare has been in hospital care for the past month after suffering a brain infection and he was moved from Starship Hospital to Kidz First, which is located at Middlemore Hospital, on Wednesday.
Once he was settled into his room on level two of Kidz First Children's Hospital, Hukatai said she noticed one or two ants crawling along the wall so she squashed them and didn't think much of it.
The next day she saw more ants on the opposite wall and then even more crawling across the roof, above the bed.
"After I saw them on the ceiling I knew there was a problem," Hukatai said. She informed the nurse and a cleaner was sent in to clear the room of ants.
However, the ants marched on.
"I saw about 10 more and got fed up. I asked to move rooms and said I didn't want to be in there anymore. That's just way too many ants," Hukatai said.
They were relocated to the room next door after it was deemed to be ant-free, but yesterday Hukatai found an ant crawling across her arm and then more on the bed.
She said she notified hospital staff again and overheard a cleaner asking a nurse: "What am I supposed to do about the ants?"
"When I talked to the nurses they said it's been happening for years. Around the windowsills they've put tape on it to stop the problem," Hukatai told the Herald.
"Surely someone needs to do something about it."
Hukatai asked to be moved again and was relocated to another hospital block late last night.
She said she would lodge a formal complaint with the hospital before Noah was released.
A Counties Manuka Health spokesperson said facilities and maintenance staff "will take appropriate action to address the issue".
"We have ongoing systems in place to deal with such issues and there are reviewed regularly," the spokesperson said.
