Former National Party MP and Cabinet minister Richard Worth has died aged 73.

A death notice said Worth passed away peacefully yesterday.

Worth served as Minister of Internal Affairs and later as the honorary consul for Monaco.

He was Epsom MP from 1999 to 2005 and a list MP from 2005 to 2009, when he resigned due to misconduct allegations.

In a family notice published today, Worth was described as a beloved father and father-in-law and adored grandfather.

A memorial service will be held at Parnell's St Mary's-in-Holy Trinity on Monday.
