The Labour MP created a storm of controversy earlier this year when he highlighted the large number of Chinese-sounding names on a list of 4000 residential purchases in Auckland. His party wants to restrict foreign ownership of residential property.
Mr Twyford said he would press ahead with a private member's bill that would ban foreign property speculation, and was due to be debated soon in Parliament.
Labour leader Andrew Little said this morning he held no concerns about Mr Lusk's plans.
"When people like Simon Lusk appear on primetime TV in a programme like that, it means their business is failing, they're desperate for work, and that's why they're doing that."
Mr Lusk was one of the key players in Nicky Hager's book Dirty Politics.
He has previously acted as a strategist for several National MPs and is a friend of blogger Cameron Slater.
The National Party now warns candidates against working with Mr Lusk.
Mr Hager's book said that Mr Lusk worked with Mr Slater to discredit candidates they did not like, and to engineer Don Brash's takeover of the Act Party.
Mr Lusk has also been linked to Labour's Napier MP Stuart Nash.
TV3 reported that Mr Nash's associates reportedly paid Mr Lusk up to $20,000 to investigate the potential for an alternative centrist party, possibly headed by Mr Nash.
Mr Nash said today he knew nothing about the alleged "hit job" planned for his colleague.
"I have nothing to do with taking Phil Twyford out," he said. "Phil is doing a fantastic job."
