With 4000 copies sold by lunchtime and several thousand already on back order, Nicky Hager's bombshell has overwhelmed the book industry.
Hager's book, Dirty Politics: How attack politics is poisoning New Zealand's political environment, launched on Wednesday night, is based on thousands of emails revealing the extent of the relationship between Slater and prominent National Party figures.
Executive director and publisher at Craig Potton Publishing Robbie Burton, said the entire first run of Dirty Politics - 4000 copies - sold out by lunchtime.
"Truth is, we've been completely overwhelmed by the level of interest," he said.
Several thousand were on order for this morning, and the printers were "going for it" until demand slowed.
"I'm thrilled that people still want to read books about a subject like this," he said.
Unity Books Auckland owner Jo McColl said she had been selling books for 35 years but never experienced demand like this.
Before the store opened yesterday, all its copies of Dirty Politics had been sold via orders.
"Nicky's books have always gone well . . . but this has just come roaring out of the gates like I've never seen before."
