NZD fundamentally is pretty weak, with all 5 of its major trading partners facing some form of political/financial upheaval. This is important to know because NZD economy is compromised in large part of its exports. However, data has shown that New Zealand has been becoming a favorable investment due to its free market policies that have kept the financial sector pretty solid.
China's market, which is affecting NZD the most and is her main trading partner, gateway at Hong Kong has seen protest that have been slowly turning more ambitious. This has helped NZD turn south, as well as the Chinese yuan. However with all eyes on Hong Kong from the international community I truly hope China will play it safe and back off a bit for a while.
