New Zealand's government has confirmed that Australia's deputy prime minister, Barnaby Joyce, is a dual citizen. The office of New Zealand Internal Affairs Minister Peter Dunne confirmed that under New Zealand law, a child born to a New Zealand national is automatically given citizenship. <br/><br/>Joyce, who leads the conservative Nationals minor coalition party, said he had legal advice that he would be cleared by the court and would not stand down from Cabinet. Dual citizens are not allowed to run for public office under Australia's constitution. Mr Joyce revealed earlier that he may have New Zealand citizenship by descent.<br/> <br/>Mr Joyce is the latest of several Australian politicians to be caught up in dual citizenship scandals.Two senators, Scott Ludlam and Larissa Waters, were forced to resign last month over their citizenship status. Another two senators, Matt Canavan and Malcolm Roberts, will also have their eligibility decided by the High Court.
