And it seems they're no longer interested in talking to their former advisors from Treasury, whose officials were left for forty five minutes waiting outside their office corridor.
They were there to talk to them about the books, to do the courtesy of briefing them.
The officials finally gave up, with a Beehive jester assuming the Nats were probably having a Christmas lunch.
In fact the only one dining out on National's discomfort was the man who Joyce said is the economy's biggest fiscal risk, Grant Robertson who of course is now in the position where he'd love to be.
Bill English struggled to take the gloss off the economy, simply observing the Government's got no excuse for not maintaining its strength but saying its approach to sharing the benefits of it was pretty messy.
Yeah but National was itself finally converted on the road to the ballot box this year by also offering a families package which they're now accusing Labour of stealing.
The Labour plan, also announced before the election, will see 384 thousand families with kids better off by an average of $75 a week while National's Budget offer in May was lifting the income of 365 thousand families by $39 a week.
So it all comes down to whether the smoko room or the boardroom carries more influence.
And while they're bickering over the figures, and who's prepared to be more generous, perhaps the impotent National opposition should reflect on an observation once made by Helen Clark when she declared she was a victim of her own success.
