Wellington City Council is reviewing its alcohol and drug policy after an alleged incident at a function in May.
The council won't comment on the incident, but it reportedly involved drunken behaviour during a party at council offices on The Terrace.
Wellington City Council chief executive Barbara McKerrow said they did not comment publicly on internal investigations relating to staff.
However, McKerrow did confirm they are reviewing the council's drug and alcohol policy to ensure they have the right checks and balances in place regarding the consumption of alcohol at work or work-related functions.
"We want to put in place clear guidelines and protocols so that we can ensure that we are responsible hosts and ensure that our staff are safe."
