In an effort to save a bit of money, we have made the switch to the cheapest One plan. We were paying $105 with Spark including Netflix. Now on the $65 One NZ plan and will drop Netflix. So far I haven't really noticed the drop in speed from 300MBps and just checked, we are only on 50Mbps so we haven't even been upgraded to 100 yet. For reference, we are a household of 4. We all stream Youtube etc on our tablets and TV and sometimes all 4 of us are watching something different at once. I feel that 100Mbps will be more than enough for us. Hopefully we will get the 100 upgrade soon.
