I've decided to only do the South-Island section of TA and afterwards travel on both Islands and do whatever I see fit. The first three months I will be walking the 1300 km that stretches over the South Island, the other 2 months are for traveling. I will be leaving on January 1 and come back home on the 8th of may.
All information about Te Araroa is located on their official website. I think it's good to start there if you are considering on doing the trail. Literally everything you need to know is on there.
Before I decided to go on this incredible adventure, I've spend hours on the internet reading blogs, websites, books,... about 'thru-hiking'. If it grabs you and it doesn't let go anymore, you need to do it! You should definitely check TA groups on facebook. There is also a lot of information to get from people who already asked some questions or you can post something yourself.
My plan is to start walking at january 8 and I have the luxury to take my time and take it slow. Hopefully my trail legs will kick in fast and I can finish before I hit 80 days. We will see!
