Te Araroa - Any thoughts?

I'm considering taking some serious time off and heading to NZ some time next year. Te Araroa supposedly opens in its compleation at the end of this year.
The thought of hiking 3000k's across the entire length of NZ appeals to me.
Has anyone done similar, in part or whole? Anyone have similar plans?
What would be the best way to do it? It takes 90 to 160 days apparently. Would it be logisticly possible to just walk from one end to the other or would I regularly have to stop for weather and/or impassible conditions.
