Hi Stephanie and Simone


Please find attached an extract from our line gradient and curvature book.


For the three sites, the Auranga site looks to be at around 639.5km, which would put it on a 1 in 100 gradient, probably a bit steep.


The Integrated site is at about 641.25km, which would put it on a 1 in 400 gradient, probably OK.


The Kiwi site is at about 641.9km, which would put it on a level grade, so OK.
