The Human Rights Commission says it does not want a change to hate speech laws - as high-profile New Zealanders warn freedom of speech is under threat in the country's universities.
Human Rights Commissioner Dame Susan Devoy this year called for politicians and others to address hate speech, saying "we need people at the very top to take some leadership on this".
That position was referenced by Auckland University of Technology's History Professor Paul Moon, when he released an open letter signed by 27 New Zealanders including Don Brash and Tariana Turia, warning free speech is under threat.
"Individuals, not any institution or group, should make their own judgments about ideas and should express these judgments not by seeking to suppress speech, but by openly and vigorously contesting the ideas they oppose, without discrimination or intimidation," the letter states.
"Universities play a fundamental role in the thought leadership of a society. They, of all places, should be institutions where robust debate and the free exchange of ideas take place, not the forceful silencing of dissenting or unpopular views."
Today and after publicity around the letter, Human Rights Commission spokeswoman Christine Ammunson said it was not advocating for a change to hate speech laws. What it did want is for Police to collect "hate crime" data as part of crime statistics.
"For example if Jewish graves are desecrated we want Police to record that crime as more than just property damage," Ammunson said.
In releasing the letter, Moon cited the case of a European student club at the University of Auckland, which withdrew its application to affiliate with the University of Auckland after criticism and fears it was a thinly veiled white nationalist group.
The president of the fledgling club said it had become dangerous to continue in the face of "appalling rhetoric" and unfounded accusations of racism.
Moon said the closure of the European student club was something to be wary of.
"If what they say is indeed racist or promoting hate, then we should expose and ridicule it, not just shut it down," he said.
Moon said he planned to send a copy of the letter to all party leaders in Parliament.
Labour leader Andrew Little said there was a difficult line to draw between protecting free speech and pushing back against statements "calculated to cause harm or incite unhealthy responses".
Personally he was "a bit of a free speech nutter", Little said.
"We do have to, and sometimes on very difficult occasions, preserve the right of people to express views, even if sometimes they are unpopular or unpalatable to us. But there is a difference between that, I think, and clearly calculatingly harmful, prejudicial statements."
Prime Minister Bill English said there was generally a "pretty tolerant public discussion" in New Zealand.
"Occasionally there are some pretty strong views expressed and I think that's important that they are able to be expressed."
In Australia, the issue of hate speech has been more controversial. This month the Australian Senate rejected attempts to water down Australia's hate speech laws.
The Turnbull Government had proposed to change the law to replace the words "insult", "offend" and "humiliate" with the term "harass".
