Australia and New Zealand are not among the usual suspects when it comes to state suppression of civil liberties. But both countries, stung by Edward J. Snowden’s revelations last year about their intelligence-gathering efforts, have been cracking down on the press: Australia has passed sweeping secrecy laws, while police officers in New Zealand recently raided the home of a reporter who had published information regarding a government scandal.

There has been little international outcry, and Washington is hardly likely to be upset: The two countries harbor the only major intelligence gathering facilities for the National Security Agency in the Southern Hemisphere, and, along with Britain, Canada and the United States, are members of the intelligence-sharing arrangement known as the “Five Eyes.”

In New Zealand, the journalist targeted in the raid is the country’s top investigative reporter, Nicky Hager, who has been working with Mr. Snowden and the journalist Glenn Greenwald. Mr. Hager has “long been a pain in the establishment’s neck,” a former prime minister of New Zealand, David Lange, once said, admiringly.

In 1996 Mr. Hager published his book “Secret Power,” which revealed the relationship between the N.S.A. and New Zealand. Mr. Lange said that he learned more about what the N.S.A. was doing in his country from reading Mr. Hager’s reporting than he did as prime minister.
