Many arrived here after their entire whanau had been tortured and murdered.
They are remarkable, quite unforgettable people to meet in person. They are also some of the bravest Kiwis I've ever met.
A few years back the children from Wellington's Moriah Jewish School began collecting buttons - one button to represent every child who was murdered by Germany's Third Reich.
Buttons arrived at the school from all over the world, along with them stories of children.
Some murdered, others left orphaned and some vanished.
The students ended up collecting 1.5 million buttons - one button for every child murdered.
These are a few of the reasons why I will never think that it is okay for New Zealanders to wear Nazi-styled uniforms.
Why? Because people wearing Nazi uniforms murdered 1.5 million children.
They did it on purpose and they would have kept murdering children if they had not been stopped.
I'm proud that New Zealanders went to fight against the Government that murdered those children, I know our own Kiwi veterans returned home with horrible stories of what they had seen.
They had seen humanity and humans at our worst.
When asked why they started the button project, one of the students from Moriah School told the reporter: We wanted to make sure the murdered children weren't forgotten.
I've written this article to help ensure that those children aren't forgotten and to make it clear that Neo Nazi fascism and racism does not belong in Aotearoa New Zealand.
This is not how we roll. This is not part of Kiwi culture and it does not belong in our future.
I totally support the marches against child abuse that will be taking place across the country but question the participation of those who'd use them as a public relations opportunity.
Some members of this organisation argue that they aren't Neo Nazis but just White Pride activists: I don't really care what they call themselves.
The reality is that their New Zealand leader has been convicted of fire-bombing a South Island marae.
The person in Masterton who has been in the Times-Age of late has vowed online that he will give his life for his white race.
Some say we should ignore these kinds of extremists but sometimes we need to stand up publicly and say that their philosophy is 'Not Okay'.
As I looked back at the man in his Neo Nazi uniform I wondered if he'd ever had the guts to meet any of those brave old ladies I have met who survived the Holocaust.
Unlike him they have seen a real Nazi uniform up close. Not just a dress-up one.
