October 2015 Te Arora Thru hike

Hello, I am a new member here and seeking advice/thoughts on travel on the South Island section of the trail. I am a experienced hiker, and normally hike by myself. While I understand and except the risk of solo travel in wilderness areas in the United States, can I reason I would be fine doing the same in New Zealand ? I'm wondering how many people travel this tract during the summer months. I'm aware of the Te Arora's growing popularity, especially with long distance hikers, but are the numbers of trampers such that I would not be likely to encounter others in some of the more remote/challenging areas of the trail ? Can any of the members provide me with an idea of the likelyhood of meeting others in this section, or should I seriously consider traveling with a partner. I would be grateful for any information provided. And would enjoy traveling/meeting other members during my travels. I normally average 20 -22 mi. (32 - 35 km.) a day. So I feel 4 months, including "zero days" to complete the walk. Thanks in advance, Dennis Dooley Fairbanks, Alaska
