(I got inspired from another post I published yesterday in the general economy section :

The deal even got down to 1114EUR/949GBP LHR-PPT *A.)
Here, you can fly from OSL with LH, SQ, NZ and SK all the way to PPT for less than 2100 EUR all long haul in PE. Most dates are around 2050 EUR.
Google flights shows those prices at a few dates (see below)
I cannot find any OTA working with this city pair which is frustrating (maybe it would be better getting in touch with a travel agent), but if you can, this routing should almost lead you to NZ Airpoints Silver.
450 TP are required, and at minimum, the routing should grant you 443 if my maths are correct (it seems to me quite low but calculators on SQ or NZ do not work well with PE) and I'd say around 30k miles on SQ but again, because I don't have booking class, I can't be precise.
