The Wellington Chamber of Commerce has two events on the 18th of June.
They have a breakfast with David Cunliffe for $45.
Then a lunch with Steven Joyce for $55.
Now they price these events based on what they think people will pay (Hence why lunch with PM with Trans-Tasman Council was $500 or so, and $85 at the Chamber).
This shows that Steven Joyce is rated more valuable than David Cunliffe!
