Singapore has a policy of mandatory conscription of young men into the armed forces, police force or civil defense force. Most serve full time for two years, followed by annual training obligations.
The ministry described Pang as an "Operationally Ready National Serviceman" indicating that he had completed his full-time service. It described him as an armament technician and his rank as corporal first class.
Pang's Singapore-based agency, NoonTalk Media, wrote on Facebook that it was waiting for more information on the actor's condition from the military and his family.
"Please bear with us and join us in praying for his swift recovery," the agency wrote.
New Zealand's defense force said a member of Singapore's military was injured during a live-firing exercise that New Zealand's military hosts each year.
Singapore's defense ministry said it was investigating the incident to determine the cause.
Pang is known for his work on the movie "Young & Fabulous" (2016) as well as television series that include "The Truth Seekers" (2016) and "C.L.I.F." (2011).
