The Yakovlev Yak-52 ZK-ADM2 (c/n 833601) I believe it obtained its NZ CofA on Thursday.
I captured it arriving back, joining overhead, at Rangiora this afternoon with Ian and Lachie flying.
It arrived in NZ marked as RA-3490K in March this year having been listed to the ZK-ADM Syndicate on 06-03-2017.
Water ratings included !
It now carries the number '83' on its fuselage.
