The Speaker of the House is reviewing Parliament's dress code over the summer break. Greens co-leader, James Shaw, has asked Trevor Mallard to consider changing the rules that require men to wear ties in the debating chamber.
Mr Mallard has invited MPs to write to him with their views, but in the meantime all MPs must obey the business attire dress code.
New Zealand Fashion Museum founder, Doris De Pont, talks about the evolution of the tie in New Zealand.
