Senator FARRELL (South Australia—Deputy Leader of the Opposition in the Senate) (14:13): Mr President, I have a supplementary question. Fairfax report that, the week before the Deputy Prime Minister finally came clean about his New Zealand citizenship, they were told by his office: 'We've had all these questions before, but there's nothing to see here. The NZ authorities have told us we don't have a problem. Barnaby established that many years ago.' When did the Deputy Prime Minister's office first contact the New Zealand authorities?
