The National Party has elected two new whips after Chris Tremain and Jo Goodhew were promoted to ministerial positions.

Whips are in charge of organising a party's MPs, making sure it has cover in the House and signing off leave applications.

List MP Michael Woodhouse will become National's senior whip and Taupo MP Louise Upston becomes junior whip.

Both Tremain and Goodhew became Ministers outside of Cabinet in a ministerial re-shuffle following the election.

There had been suggestions National would appoint three whips to deal with its swollen ranks.

But they stuck to the normal two.

Woodhouse and Upston were elected at National's caucus meeting this morning.

Prime Minister John Key said both were hard-working MPs.

"I am confident they will do a good job in their new roles. I congratulate both of them."
