Teams have to come up with a theme for horses and riders to wear costumes, then choreograph a music routine.
The Wanganui club chose the movie Sister Act and performed as nuns, placing second in the phase.
They also got third placings in Games and Rescue Relay, came fourth in Formation Jumping and Riding Club Mount, and eighth in Working Hunter.
Accumulated points meant Wanganui just finished runnerup to the Le Trec NZ club from Wellington, who were at their inaugural NITE and had phase results of three first placings, two seconds, a sixth and an 11th.
Kapiti Riding Club hosted the event to mark the 40th anniversary of the NZ Riding Clubs (NZRC), of which local Brian Pyke was a founding member and instrumental in getting NITE underway.
The Wanganui team consisted of club president Stacey Houlahan, riding Charlie, vice president Melanie McGovern (Zarla), Kelsey Harrison (Roman), Lynette O'Leary (Herb), Susan Cameron (Mia) and Molly Milne (Wonder Jump).
