Ms Sandhu will take a maximum of 12 people for a 16-day tour to experience the sights and sounds of India, including her niece's traditional Indian wedding in November.
"All tours are designed by me. I like to immerse them in the culture so they feel part of the culture that's in front of them. India is a great country of diversity," she said.
Ms Sandhu has been living in Queenstown since 1993, when she opened Little India restaurant.
She said Queenstown, and New Zealand, had become very multi-cultural and New Zealand people were open and willing to learn about other cultures.
"Being brought up in India but living so long in New Zealand I can understand where Kiwis are coming from and I can understand where Indians are coming from.
I can speak both their languages and am able to marry the two together very well," she said.
She ran three tours, in 1997, 1998 and 2000, but stopped to concentrate on her restaurant businesses.
Ms Sandhu opened a Mantra Restaurant in Christchurch and in Arrowtown in 2004.
This year, her friend urged her to take her on a tour of India.
It took Ms Sandhu about six months to put together and organise an itinerary for her fourth tour to her homeland.
She has six confirmed bookings so far.
The cost is $6250 per person for twin share ex Delhi.
It does not include international flights to Delhi.
It includes all accommodation, food, transfers, excursions and sightseeing tours.
The tours include the Taj Mahal, an elephant ride, boat ride and a visit to a deserted red sandstone city.
The tour takes in Delhi, Jaipur, a night in the Manvar Desert Camp, Jodhpur, Devigarh, Udaipur and Chandigarh.
They will visit the Jain Temples of Ranakpur in the Aravalli Valley, the City Palace and Lake Palace.
She said the highlight of the trip will be an opportunity to share in a four-day family wedding, including three ceremony lunches and dinners.
"We will visit places people do not usually go but should not miss out on.
I don't want people to feel like tourists.
They should feel part of the culture instead of going to all the tourist traps," she said.
People could also opt to extend the tour by five nights to take in Goa and a Bollywood tour in Mumbai for an extra $2300.
Ms Sandhu sold her Queenstown and Christchurch businesses but is a hands-on owner of Mantra in Arrowtown.
She is passionate about sharing her culture and organises a Bhangra night in Arrowtown to celebrate the traditional folk dance.
About 220 people attended the event at the Athenaeum Hall this year.
All her four siblings live in New Zealand, including her sister Sukhi Turner, who was Dunedin mayor for nine years.
