I've put the Real NZ Christchurch/NZCH prepay option back in the Store, for a short time only. Still no definite release date,
but I am hoping it will be April 2019.
I had hoped to have a beta ready by the end of March, but March was almost a complete write-off, due to poor health, and the Christchurch shootings. I'll review progress at the end of April and report back.
