Lim was involved in the Canterbury Malaysian Students Association and the Canterbury University Tramping Club. He was a musician and Sunday school teacher at the Every Nation Church.
DoC director of operations for the eastern South Island Andy Roberts said Lim's absence was noticed when he failed to respond to radio calls from the Pinnacles Hut warden.
"Tumbling down the north side of Mt Somers are huge columns of rhyolite which form one of the best climbing areas in Canterbury. The routes are long and sustained outings up grooves and aretes up to three pitches high."
Roberts said that at any one time during summer, DoC had about a dozen voluntary wardens stationed at huts in Canterbury.
