"All Indians, we celebrate like how you celebrate Christmas," Monisha said.
"It's like celebrating one of the biggest festivals in India, which is all about festivity, mood and brings out flavours. We give gifts - we create lots and lots of delicious food."
The month of Diwali is known as an auspicious time when people start new enterprises and according to Vishal, buy houses or extravagant things.
"Some people buy new cars, new houses, and they'll start their business, so it's considered to be a very good period in India for starting a new life," he said.
There is a spiritual dimension, prayer is always first, followed by gathering to light fireworks and other less esoteric pursuits.
"My wife had a lot of Indian sweets," Vishal said. "So we were still able to celebrate a small celebration. The candles, the diyas and the oil lamps, as part of the tradition. It was more of a formal family event this year."
With Covid restrictions easing, it's hoped Rotorua's Diwali celebrations will be back in force next year.
