Premier Gladys Berejiklian says she's pleased to be giving evidence at a NSW Independent Commission Against Corruption investigation into disgraced former Liberal MP Daryl Maguire.
An ICAC witness list issued on Thursday revealed the premier had been summonsed and was the only person scheduled to appear on Monday when the anti-corruption body's hearing enters its fourth week.
"I'm pleased to be assisting with those inquiries. And it wouldn't be appropriate for me to elaborate," she told reporters.
Mr Maguire was forced to quit the Berejiklian government in 2018 after a separate ICAC inquiry heard evidence he sought payments to help broker deals for property developers.
The current inquiry has heard evidence Mr Maguire sought payments to help broker deals for Chinese property developers.
It's investigating whether Mr Maguire breached the public trust by using his public office and parliamentary resources to improperly gain a benefit for himself or for G8way International - a company he "effectively controlled".
The premier was dragged into the saga this week when the ICAC heard Mr Maguire gave a western Sydney landowner - Louise Waterhouse - Ms Berejiklian's email address to help her lobby for rezoning changes that would benefit her parcel of land.
In a recorded phone call aired at the ICAC, Mr Maguire passed on the email address and suggested the premier would be able to provide a "tickle from up top".
Ms Waterhouse told the inquiry Ms Berejiklian never responded to her email and no zoning changes were made to her property.
Ms Berejiklian's former chief of staff Sarah Cruickshank is scheduled to give evidence at the inquiry on Friday.
Mr Maguire will also give evidence at the inquiry from next Tuesday to Thursday.
