The Te Araroa Facebook page was really good. It helped with planning the trip and through Facebook we both met people in Auckland who had either done the trail, or were also planning to do it. Along the trail it enabled the trail community to warn those behind of any difficult sections and make suggestions. Even if you are not a Facebook fan (which I'm not) I would recommend signing up even if you only use it for the trail.
Madeleine and I crossed rivers linked together when the water was high and or fast moving. It is a good technique and much much safer - if one foot slips between you there are still three feet on the ground. Madeleine and been on a river crossing course in New Zealand and it would be worth considering if you are not experienced.
I found my walking poles to be very helpful in water crossings. Madeleine walked without poles so in some places I would cross first and then throw the poles back for her to use. When we crossed together, we each used one pole in the outside hand.
Sense of achievement
Having completed the trail and fully recovered we have returned to our respective countries and slotted back into 'normal' life. But inside us there is still a sense of pride and achievement in knowing that we tramped the Te Araroa!
Our memories have softened and we can't quite remember how horrible it was to put wet clothes on day after day, exactly what wet boots feel like and how low the low points were.
We both really miss the trail. Nicke and Cookies' video sums up the trail nicely.
