New Zealand's measles outbreak has been exported to the United States, according to American authorities.
A report by the US Centers for Disease Control and Prevention this month lists New Zealand as the source for two of the cases of measles imported into the US this year, more than the number that had come from significantly large countries such as China or Australia.
The US had experienced 1249 cases of measles and 22 outbreaks this year, with 81 cases imported from other countries.
That compares to the 1694 cases here. There are 1383 cases in the Auckland region alone, according to the Ministry of Health.
National Party health spokesman Shane Reti said the scale of New Zealand's problem showed the Government had been slow to act and said vaccinations for those who needed them were still being delayed.
