Coming to visit

Hi, Have a general plan to hike NZ from tip to toe. Here's what I envision... 2 months - Dec/Jan, or Jan/Feb. Which would be more practical in terms of travel/weather/etc...North to South or South to North. Is 2 months enough...would like to include all great walks and their connectors. I average 10-20k a day. Couple of general questions... Of course huts are great, but I intend to tent the majority of nights. Is tenting permited on all/most trails (excuding private land)? Fire? Are camp fires allowed (assuming low hazards)? I treat fire with highest regard...always build tiny fires...boil a pot, warm face & hands...put it out! Transportation to and from trail heads - generally available? Cost? ( I realize cost varies with distance/time/etc)but generally... Am I up for it? 2009 I hiked the West Coast Trail - 77k in 6.5 days. 2010 - I hiked the Juan de Fuca Marine Trail - 50k AND the WCT in 9.5 days. All self contained with no re-supply. http://www.mediafire.com/?sharekey=p1zlg9m4e8a46 This link will show you some pics from the two years. And absolutely anything else you care to share. As time draws closer, I'll start firming up details. Generally I do not believe in reserve-systems but sometimes you gotta bend! Isn't my intention to ignore the cities or the people. With only 2 months, I suspect most of my time will be on the trail.
