Some of the country's Internet Service Providers (ISPs) have begun blocking around 7,000 websites on a secret Government blacklist.
The filter is aimed at restricting sites containing child pornography.
But critics claim it gives the Government a free hand to censor anything else it disagrees with.
The World Wide Web is shrinking a little for New Zealand surfers.
An internet filter set up by Internal Affairs is already blocking some websites for customers of two service providers - Maxnet and Watchdog - and others are expected to follow.
“Well it's got a very narrow purpose, in that it's about filtering or blocking access to websites that contain images of child sexual abuse,” says Keith Manch, from the Department of Internal Affairs.
But Mr Manch admits the filter isn't a silver bullet.
“So it's not about solving the whole problem of images of child sexual abuse being available on the internet, or being traded or possessed by people. It's just one of the strands of the rope if you like,” he says.
But online freedom campaigner Thomas Beagle, of Tech Liberty, says it's a slippery slope, with filters overseas quickly expanded to include other material.
“Well we're giving the Government a tool which will allow them to block content, and governments are very keen on using tools once they get them,” he says.
He believes it's a sad day for internet freedom.
“We're joining the group of countries which includes China and Iran and other countries along those lines, who I really wouldn't want to be associated with when it comes to freedom of speech,” he says.
But not all ISPs are expected to sign up for the voluntary filter.
Orcon said in a statement that it has concerns over the filters’ operation and effectiveness:
“Currently we do not have enough detail to be able to address these concerns to our comfort…this is why we have not implemented the filter.”
The big providers like Vodafone and Telecom are expected to join up soon, but Internal Affairs is encouraging ISPs to let customers know if their web surfing is being filtered.
