I managed 1 shiny on Saturday and 5 on Sunday, both days were spent in Takapuna. I've got no idea how many I caught/checked (I always forget to check the count before the event starts).
I haven't evolved any of the shinys yet, with a limited number I feel that I'll be unlucky and won't be able to get the full set. Maybe I can find someone to trade duplicates with.
I'm sitting on 2.1 million stardust.
