The son of murdered NSW police accountant Curtis Cheng has called on Pauline Hanson to stop citing his father's death in comments about Muslim migration to Australia and the risk of terrorism.

Canberra teacher Alpha Cheng has accused the incoming Queensland senator of promoting fear and exclusion, saying his family has suffered from hate promoted by Ms Hanson's One Nation party since the 1990s.

Ms Hanson cited Mr Cheng's murder during an appearance on ABC TV's Q&A program this month, and her party mentions his death in its policy on Islam, which includes controversial calls for a royal commission into the religion amid claims it is a political ideology and not a faith.

Curtis Cheng, a longtime police accountant and father of two, was shot as he left the NSW Police Force headquarters in Parramatta on October 2.
