Amazon’s Kindle eReader, which it launched last month, has been banned from sale on its website.
The company said the ban was made following concerns about “unlawful and malicious” behaviour on its site.
The ban covers Kindle owners in Australia and New Zealand, as well as those who buy books on Amazon.
“Amazon has received numerous complaints from readers about inappropriate behaviour on the site,” it said.
“The company has determined that the content of this material does not reflect the values of Amazon or its users.”
The ban does not affect any other Amazon-owned Kindle products, including eBooks, e-books, ebooks, and books.
“While Amazon does not endorse any specific political party, it believes that the values we stand for are aligned with those of our users.”
Amazon said it was notifying affected customers that they could purchase the new Kindle by searching for “Amazon Kindle”.
It said it would be taking a number of measures to make sure customers were informed of the changes.
The decision came as Amazon and the US Department of Justice announced a $US1.5 billion settlement in the antitrust case brought by Apple against the internet giant.
Amazon has not said how many of its users in Australia or New Zealand have purchased a Kindle ereader, or what prompted the decision to ban it.
