"New" De Havilland Devon graces the register

Popping up on the ZK register on 13/12 was De Havilland D.H. 104 Devon C.1 ZK-DVN/2   with the Central Flying School (RNZAF) at Ohakea. 

This example has languished at RNZAF Woodbourne as an instructional airframe since October 1981 as INST215 having being shipped to NZ back in September 1953 and used as a communication aircraft.  It moved to Whenuapai's number 40 squadron in 1977 and to number 42 squadron at Ohakea in 1980. 

Does anyone know the future for this aircraft?  I presume it will join the DH82 and Harvard at Ohakea, but why put on the civilian register?

I caught up with it and several other Devon's outside at Woodbourne in 1991:
