The health expo would include massage, reflexology, skull healings and pain management sessions.
"Basically, you name it we have it.
"They will be 15-minute treatments. On the day you book in for one of the treatments and you get an appointment."
There would also be another area for workshops and performances.
"We have belly dancing, Bollywood dancing and salsa. We also have a whole lot of stallholders with people giving free advice on health topics. Basically, the idea is we don't know what we don't know, so it's about exposing people to different ideas."
Formerly from South Africa, before setting up a psychology business in Napier six years ago, Nagar had now organised similar events for the past four years.
Last year about 500 people attended and it was hoped a similar number would take part this year, she said.
"I know there will be a lot of familiar faces. There's a lot of people who have been there since the first Mandela Day. All the treatment providers say it's just such a different buzz they get from any other workshop or expo because the energy is so different, even though they are working hard all day, they are really buzzing."
A timetable of events would be posted online and on the International Mandela Day Health and Wellness Celebration Facebook events page.
