Leuchs (30) sealed his selection with a series of top performances in international events this year and is ranked in the top 16 in the world.
The France-based rider had two top-10 finishes in the World Cup series to confirm his top status in the sport.
He is one of 17 people associated with Otago who will be competing or in an official capacity in Beijing.
The most experienced is Dr Dave Gerrard, who finished sixth in his semifinal of the 200m butterfly at the Tokyo Olympics in 1964.
He has held a series of medical and managerial appointments at Olympics since, including being chef de mission.
He will be on the medical commission in Beijing.
Sport Otago chief executive John Brimble is impressed by the calibre of the people from the province who are part of the New Zealand team for Beijing.
"It is a comprehensive list reflecting the depth and breadth of sporting strength within Otago," Brimble said.
He was particularly encouraged by the range of coaching and support staff who had been "recognised for their knowledge, ability and success with their athletes".
Attending his first Olympics is cycling coach Craig Palmer, who is a sports scientist with the cycling team.
He is the personal coach of Alison Shanks and Hayden Roulston, who are both members of the cycling team.
The triathlon coach for the Games is Dr John Hellemans, who was named the Otago coach of the year at the Otago Sports Awards dinner last May.
He is the coach of Chris Gemmell and Andrea Hewitt, who are both members of the triathlon team for Beijing, and Wanaka's Nicky Samuels, who is a non-travelling reserve for the New Zealand team.
Also attending their first Olympics are Raylene Bates, who is the athletics team manager, and physiotherapist Helen Littleworth.
Former international marathon runner Paul Allison is on the 160-strong TVNZ media team.
Allison (48), the chief executive of the Central Lakes Trust, will concentrate on athletics and will give a comprehensive coverage of the track events.
Allison will be based at the main stadium and will be part of a team including Nigel Avery, who will look after the field events.
Greg Henderson (31) is an experienced international cyclist who has honed his skills as a professional on the roads of the United States and Europe.
He won the world title in the 15km scratch race in 2004, won the Commonwealth Games gold medal in the points race in 2002 and was fourth in the same event at the Athens Olympics.
He will contest the points race and madison in Beijing.
Rower Hamish Bond (22) will stroke the New Zealand coxless four at Beijing.
He stroked the four that won the world title at Munich last year.
The crew won the team section at the Halberg Awards and was named by United States based Rowing News as the World Crew of the Year. Shanks (25) has moved steadily up the world rankings over the last 12 months.
She clinched Olympic selection with her seventh placing in the 3km individual pursuit at the world championships in Manchester.
The Daniels sisters, Nina and Lisa, reached the podium twice in international synchronised swimming events in the past 12 months when winning the bronze medal at the Canadian and Chinese Opens.
