Nadia Lim opens up about why making Nadia's Farm is so important to her

Nadia Lim's new show premieres tonight on Three - a project that is hugely important to the MasterChef New Zealand star.

Nadia's Farm follows her and husband Carlos Bagrie as they take on their biggest venture yet - taming 1200 acres of rugged Central Otago farmland at Royalburn Station.

For Lim, the aim of the show is to reconnect New Zealanders with the land, generating a more informed understanding of where their food comes from.

"Maybe a generation back, most Kiwis had some direct connection to a farm - whether through an uncle or aunty, grandparents or close friends - but that would be more rare than it is common these days," Lim, 36, told Newshub.

"These days most Kiwis probably haven't even set foot onto a real, working farm and therefore don't have much of a connection with how food is produced on scale and actually gets to their plate."

Kiwis are familiar with seeing Lim on TV - but the Lim in Nadia's Farm is very different to the Lim we've seen on the likes of MasterChef, which she won in 2011. 

And it's not just the gumboots, jeans and plaid shirts she wears while working hard on the farm; it's the deep sense of passion she has for producing food, rather than simply cooking it.

"I got to the point where I felt like a bit of a phoney. I was so involved with telling thousands of people how to cook, what you should be eating, to use this recipe - but I realised I wasn't involved in those ingredients," Lim said.

"I don't actually know - deep down - how those ingredients get here in the first place. I thought if I'm going to be serious about completing that full cycle of our food, I need to be involved in primary production and really understand the journey of that ingredient before it gets to your plate. I almost felt that it was a deep responsibility I had to do that."

Nadia's Farm premieres at 8:30pm on October 5 on Three and ThreeNow.
