Dame Lowell Goddard has been asked to give evidence to a United Kingdom select committee over newspaper allegations about her conduct while chairwoman of the child sexual abuse inquiry.
British Home Secretary Amber Rudd, replying to questions in the House of Commons, said she had asked the former high court judge to appear in front of the Home Affairs Select Committee to answer questions about her departure from the role and allegations about her conduct.
Dame Lowell resigned from the troubled probe in August, days after the Home Office was made aware of claims about her "professionalism and conduct".
Dame Lowell has strenuously denied allegations against her, describing them as "falsities", "malicious" and part of a "vicious campaign". She has consulted lawyers in London over the allegations.
When Dame Lowell quit the inquiry, the third chair to do so since it was launched in 2014, she said the probe needed to be overhauled, saying "there is an inherent problem in the sheer scale and size".
Dame Lowell's replacement, Professor Alexis Jay, said she hoped most of the inquiry's work will be completed by 2020. Jay is due to appear before the Commons Home Affairs Committee today.
