Hi Julian.
We're based out of Christchurch.
Some comments back to you.
I like #12 - can you make the kiwi a bit stronger? it's almost too soft that folk outside NZ won't see what it is.
But I do like the South Island graphic - links our area strongly.
I intend to place SUBWAY logo over / on the finished graphic - and the kiwi icon works best for this (SUBWAY logo in bottom r/h corner).
Can you try this - layer the circle (with either South Island or Kiwi) on top of the blue rectangle, place it maybe 80% weighted towards left hand side of rectangle. Place the "Office of the DA" & "South Island, NZD" text to the right. Place "Saving the world one sandwich at a time" bottom, in front of reflection.
What do you think - perhaps to busy?
