After enjoying the 20% discount code posted by easternculture, I was looking for another deal for a short Airbnb stay during the New Year. Thanks to shaiguy's comments in easternculture's earlier post, I was able to use the 10% discount code for our new booking (saved me $72, every little bit helps :). This does NOT need to be your first Airbnb booking.
Booking Period: Now until Dec 31, 2015
Stay Period: Now until Jan 31, 2016
Code can only be used once per user
I have an Australian Airbnb account but made the booking via the Airbnb HK site, just to be sure I get the discount (however I am not certain whether this is absolutely necessary), and used the coupon code "CITIHK552415" which OP "Vincent" kindly posted. The transaction was in AUD.

Good luck, be safe and enjoy the holiday festivities!
Edit: To connect to a Hong Kong VPN (Thanks to shez1212):
Use www.zenvpn.net or http://www.proxy-listen.de/Proxy/Proxyliste.html
(I used FreedomVPN myself)
Optus customers prepaid/postpaid and internet or homephone get 50 dollars off airbnb too, looks like a generic code you get
