Hi there.
Have seen quite a few large jets at Taupo before. The runway length isn't a problem really and the strength is more than Nelson which gets in large biz jets much more often that Taupo. The Apron is going to be Extended soon so park will be no problem.
Did you land here in February 2020 in a G650? I came out and saw it!
Would you come back if that was you? 😂
