The Epidemic Response Committee is hearing from tourism industry representatives struggling through the COVID-19 crisis.
Treasury Secretary Dr Caralee McLeish will also appear before the committee after her and Acting Deputy Secretary Bryan Chapple pulled out Tuesday, sparking outrage from Opposition MPs.
MPs will hear from the CEO of Hobbiton Russell Alexander, as well as representatives from Volcanic Air Safari, Totally Tourism and Hennessey's Tavern.
The Epidemic Response Committee is a group of 11 MPs, the majority of whom are in Opposition, who meet via videoconference with the purpose of holding the Government to account on its coronavirus response.
National leader Simon Bridges chairs the committee, and is joined by four other National MPs, three Labour MPs, one Green Party MP, one New Zealand First MP, and permanent member David Seymour, leader of the ACT Party.
