Mary Harris told the committee that a requirement to be effective and efficient in some situations was inconsistent with reality.
"For example, Opposition members may see it as their legitimate duty to obstruct the progress of controversial Government legislation by filibustering in the House," her submission said.
"Such a debating technique is time consuming and does not necessarily align with the usual perception of business efficiency."
The bill should not tell MPs how to do their jobs, she said.
"How members discharge their duties is a matter for them as members of the House and any attempt to dictate the way that they carry out their responsibilities could be regarded, in my view, as fettering the privilege of the House to control its own operation."
Labour MP Trevor Mallard said every party in every democracy used the filibuster technique.
Mary Harris also expressed concern that the authority for funding was to be split, with responsibility for MPs' travel, and accommodation allowances for MPs and ministers, to go to the independent Remuneration Authority - which already decides on MPs' pay and allowances. The Speaker is to keep control of the funding for party and member support funding.
Mary Harris said getting MPs to Wellington and accommodating them there was fundamental to MPs carrying out their roles in Parliament.
