An Australian euthanasia campaigner is now allowed to bring a modified version of his banned book into New Zealand.
Philip Nitschke was detained at Auckland Airport when he arrived on Thursday night.
Customs officers seized two copies of his DIY suicide guide.
But he says the copies he brought in have been altered to appease New Zealand's chief censor, after the book was banned in February last year.
Dr Nitschke says a detailed explanation was given as to why it was not allowed in the country.
He says offending passages have been removed, and the book will be reviewed again by the censor.
Philip Nitschke says there is a good chance the new edition will find its way into New Zealand book shops.
