New Zealand - South Island doodles

I'm making a gift for my brother and his girlfriend, who've just bought their first home in New Zealand. I thought a doodle-filled version of the islands of New Zealand would be fun, then @laurajwilkinson suggested  that I should sneak in a Kiwi into the doodles, and it snowballed from there! I've completed South Island, and I've hidden 7 stylised birds (kiwi and pukeko being the two most recognisable) and 4 lizards in this. Can you spot them?

Next up: North Island!
