Comedy is always a challenge, he concedes. But the international circuit is always looking for new people, so luckily funny is all you need.
Is frail former South African president Nelson Mandela fair game back home?
No, people love Mandela jokes, he says. As long as you aren't crazy offensive then people enjoy it.
And the controversial African National Congress, who continue in power in South Africa?
The ANC is always fair game and most of the time they're the main target of comedians in South Africa because they're the ruling party, he insists.
His own heritage has been the source of subtle mirth, with his maternal grandfather jokingly calling him master, though the humour underscores some deeper issues affecting South African society.
There are many divisions around race which people are still working to mend, he admits.
Comedy may be one way to help heal the nation's wounds, or at least take people's minds off their problems, providing of course there are more comedians like Noah taking the stage and storming the airwaves.
The scene in South Africa is growing fast and it's great, he enthuses. It's raw, unfiltered and shaping the country.
Can it wash away the wounds inflicted by the nation's racist past?
Apartheid is a sensitive topic too, but it can also be done, he says.
Which brings us, circumspectly, to the inevitable. Got a good Oscar Pistorius joke?
Not yet, but I'm working on it.
Feel free to bother Noah backstage at his Auckland shows, at his hotel or in our streets with any and all suggestions. As a man of few words, at least in interview, he may need yours.
