Caught at Motueka was this Wills Wing Falcon 3 Tandem 19G c/n 29370.
Note that it is "two up" and the selfie camera out front.
The means of getting airborne is by aerotow - as below.
The towplane is the Moyes Dragonfly C ZK-DGF (c/n C85).
Above we see "19G" being readied in the left background, with the Dragonfly ZK-DGF ready to taxy out and the dreaded "Blue Bus" on the right.
