Online retailer Amazon have removed an electronic version of Ted Dawe’s Into the River after it was slapped with an interim ban earlier this week.
The ebook version of the novel was available for purchase in New Zealand for some time after the restriction was imposed.
Amazon did not respond to requests for comment.
The legality of selling the ebook in New Zealand is somewhat murky, as the current law was written in 1993, long before ebooks became prevalent.
"We are advising anyone considering importing the book to get legal advice," a Department of Internal Affairs (DIA) spokesman said, echoing advice on its website.
"We won’t ourselves be giving any blanket advice because each individual’s intent may be relevant."
