I think the orange insect is a wasp (spider is another obs).

This wasp walked backwards firstly dragging the spider off the track, under the manuka and down into a drain, a distance of about 2m.

Next the spider got dragged 7m up the drain (this is going uphill) and then into a hole in the side of the bank. The wasp then came back out, dragging the spider and moved it to another hole in the bank.
