A 75 year old UN declaration still holds sway over New Zealand's legislation and conduct. But the Human Rights Commission sees threats around the corner.

New Zealand has recognised international human rights laws since signing a UN declaration 75 years ago, but that doesn't mean we're great at upholding them.

This week marks the 75th anniversary of the Universal Declaration of Human Rights.

But is the agreement New Zealand signed up to at the UN so long ago still relevant?

And are assumptions that we're doing just fine in this area starting to look a little smug?

Today on The Detail, Wilhelmina Shrimpton looks at the declaration, what it means for us, and the areas where we are falling down - as the new government plans to change the inner workings of the Human Rights Commission, and its coalition partner ACT declares it should be abolished all together.

New Zealand's acting chief human rights commissioner, Saunoamaalií Dr Karanina Sumeo, says the declaration is "almost timeless because those fundamental rights are as relevant to us today, and probably will be relevant for humanity going forward".

They've been influential in interpreting New Zealand law, she says. The document is a global road map that lays out 30 human rights including the right to freedom, the life free of discrimination, freedom of expression, gender equality, the right to access education, health and housing.

It has formed the basis for our domestic laws, and a lot of them are encapsulated in our Bill of Rights.

The 192 countries who've signed up to it are monitored to see how they're upholding the guidelines, and New Zealand is up for a review next year.

"One of the roles of the Human Rights Commission has is we also have the ability to go to the UN, and provide our own view of how our government is doing, how our society is progressing - and we may have a different view to government. And that's completely all right."

That doesn't mean the government can't muck with the commission, as we saw last week, with new Justice Minister Paul Goldsmith refusing to express confidence in commissioner Paul Hunt.

Dr Sumeo says the commission will present to the government based on the voices of our communities, and while we have invested in changed laws, "actually, some people's reality still hasn't changed".

She says it's ironic that while we were the first country to give women the vote, our gender pay gap is still too big.

The Declaration is not binding and each signing nation can pick and choose parts to uphold, so does it actually have enough teeth to make a difference? …
