I have also received an envelope from my pen pal of New Zealand. Aside from an interesting letter, it is a surprise to receive two mint stamps too, one of them which happened to be the Year of The Ox stamp:

The cute envelope. Note that the postage rate of this letter from New Zealand to Malaysia - NZD 2.30! It's quite expensive!

On the left: A mint self-adhesive stamp with the face value of NZD 45 cent
On the right: A mint Year of the Ox stamp with the face value of NZD 50 cent, issued in 2009
It's my first cover from New Zealand. Thank you very much, Geena.
