"A lot of noise is being generated by the screams and yelling of delight from the children using the park and people talking loudly," said the council's local and sports parks manager, Jane Aickin.
"It is great to see children enjoying the park, but the reality is that it is causing a problem for neighbours."
Several neighbours immediately adjacent to the park contacted the council to say the noise from users was impacting on their quality of life.
"We know this [flying fox] closure will disappoint some people, but we need to address residents' complaints about noise," Ms Aickin said.
But, the council said most of the planning and designing of the playground took place ahead of the homes being built.
Details were provided to developers of Stonefields, Todd Property, to include on maps and information for prospective homeowners. The council would work with the Orakei Local Board, the community and stakeholders to consider next steps, including moving the flying fox.
Local board member and parks portfolio holder Kit Parkinson said the park has been a hit with children.
"We worked with local school children on the design of the park and they love it. We'll do everything we can to ensure this remains a valuable local community playground."
