Auckland Council's put in place safety measures at a popular indoor pool complex after a man's finger was ripped off on a water slide

The man in his 40s got his ring caught in a bolt while attempting to swing into the slide at the Mt Albert Aquatic Centre in December.

Auckland Council says the bolt wasn't intended to be used as a grip point.

Fortunately surgeons were able to reattach the man's finger.

Measures introduced including removing fixtures at the slide entry and reviewing and updating slide user information.

A WorkSafe spokesperson said a follow-up assessment will be done in February, to check the health and safety systems and ensure compliance.
