Jandals. That's what Ed Sheeran will have to learn about if he wants to become a New Zealand citizen.

Ahead of his tour of the country in March, Ed recorded a video message for fans saying: "I'm not yet a citizen of New Zealand but I'm working on it - hook me up Prime Minister, please."

PM Jacinda Ardern responded with a couple of questions testing Ed's knowledge of the country.

So Newsbeat got some New Zealanders to give us some insider tips.

Firstly, what are Jandals?

"They are probably as close to the New Zealand national dress as you can get," says Casey Dalton, a New Zealander who now lives in London.

"Aussies call them thongs and you guys call them flip flops.

"In summer it's a singlet stubby (short rugby shorts) and jandals every day."

Alyssa from Wellington keeps up the fashion theme.

"Everyone wears bare feet in the supermarket. Shoes aren't compulsory," she says.

"People wear bare feet all year round, even in the winter."

And there there's pie. Even the police in NZ get involved.

"Always blow on the pie" says Alyssa. "He needs to know about this because Kiwis love pie."

If she was giving Ed advice on where to go to experience some of New Zealand's scenery, Alyssa has one destination in mind.

"Tongariro Crossing is one of the most beautiful day walks in the world. It's in the middle of the North Island and is a volcanic area."

"New Zealand's landscape is very green, mountainous and natural. There is so much untouched land."

"The beauty of New Zealand is it's the only country in the world that has every type of climate," says Genevieve, who's from Oamaru in the South Island.

From the tropical far north, you then "head down to the south which is very close to the Antarctic, so you've get your freezing temperatures."

So what else do you need to know if you're planning on moving to New Zealand?

"Rugby and the All Blacks is our religion. So Ed if you want to be a citizen, you've got to be willing to accept this," Casey says.

"In Wellington, the wind is brutal," Casey says. "Umbrellas are obsolete and you'll be laughed at if you try and use one."

For Genevieve, the sun will be the biggest obstacle for Ed.

"First bit of advice for Ed, definitely use SPF50 plus with his ginger skin. That hole in the ozone is brutal."
