Mr Hewitt, a technical specialist at the regulator, will be the event’s ‘guru speaker’, as Paraplanners convene in large teepees, in Aynho, Northamptonshire.
Mr Hewitt joined the regulator in 2010 and has spent his time concentrating on the supervision of firms delivering financial advice to retail consumers.
Prior to that he worked in the financial advisory sector, holding a variety of research and Paraplanning roles.
He will be one of a number of expert speakers.
More than 100 people are set to attend the event, now a major fixture in the Paraplanner calendar. Some will don warpaint - a Powwow tradition - to get into the spirit of the get friendly get-together.
The Western-themed 'unconference' where the agenda is decided by attendees will feature campfires and face paint to accompany the informal discussions.
Paraplanners initially met last night ahead of the event for a meal – or ‘Chowwow’.
The event is sold out and organisers gave the option of two ticket prices - £30 or £50 depending on how much visitors want to support the Powwow financially.
