A man is in custody after allegedly assaulting a security guard at a South Auckland IRD this afternoon.
One witness told the Herald a woman guarding the Manukau centre had been kicked and punched during an assault.
An IRD spokeswoman said there had been an incident between a customer and an on-site security guard.
"The female security guard is shaken by the incident in which she was pushed to the ground," she said.
"She is being cared for by IR staff. All staff and customers on site at the time will be offered help and support after the incident."
