I was reading this article https://www.nzherald.co.nz/business/nzs-biggest-data-hogs-re…
and when I was reading this part "Specifically, a new monthly fibre plan would offer download speed of just 40Mbps and upload speed of just 10Mbps - or barely faster than VDSL, the fastest form of copper line - for a wholesale price of $39 per month (as long as retailers pledge to see it for no more than $63)."
I remember seeing this earlier as a competitor to fixed wireless but I just realised.
I was thinking if skinny's base 100/20 > 300/100 is 6 months free, it would be $39 per month ($78/2). Since this is a higher version it will definitely be more than the wholesale price of $39. These costs paid by skinny to chorus should be fixed, and would be higher than $39 per month, yet they sell it to us for $39 per month. I can't imagine even with the customers who stay behind, how they are able to make a profit, as it seems to me they lose money for every person that leaves in a year. I am a bit confused, does anyone know the wholesale price of the other plans?

I think a lot of people just don't change broadband providers once they are signed up.
Whether it's too lazy to change or just don't realise how easy it is to change, after the first 12 months I'm sure they make plenty of money.
