Good luck ever actually making use of that download speed. And your upload speed is stuff so hope you don't need anything that needs more uploading (hosting larger servers)
NZ is behind time with technology. We get Fibre introduced in like, 2019.
1mbps is the max upload speed the line will take, regardless of plan, anywhere in NZ.
The only reason I get that DL speed is because I live in a business district :}
