The Epidemic Response Committee is hearing from Dr Ayesha Verrall, an infectious disease expert, who independently audited the Government's contact tracing and found that it needs to increase.
"The capacity of the 12 Public Health Units in New Zealand is the primary factor limiting New Zealand's ability to scale up its case management and contact tracing response to COVID-19," she said in the audit.
Lawmakers will also hear from Rod Drury, the founder of online accounting software company Xero, as well as KPMG's global head of agribusinesses Ian Proudfoot.
Business advisor Traci Houpapa will also present to the committee, along with journalist and researcher Max Rashbrooke, and executive director of the think tank The New Zealand Initiative Oliver Hartwich.
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.
