NSW Opposition Leader Chris Minns won't call on the premier to resign after Dominic Perrottet admitted he wore a Nazi costume at his 21st birthday.
Mr Perrottet made the admission on Thursday, apologising to the Jewish community while saying he had no plans to quit as NSW premier.
Mr Minns said it was a mistake for Mr Perrottet to have worn the costume while adding it was important to acknowledge the premier had apologised.
