Hence the confusion about this being a 'trial' and TZ following up with the statement I posted saying that it wasn't. Unfortunately it's vague either way and with the so called confidentiality agreement we won't know how large it is.
It should be noted that the postandparcel article hasn't quoted SingPost at any point
I do agree that TZ doesn't have a great communication history. But I would have sold up recently and called it a day if I didn't think the TZ share price would be quite a bit higher in the next year.
Up to you what you do, but you could always sell at a 'cheap' price if you wanted to.
