Despite the growth of the cloud, bandwidth-intensive Netflix and gaming mean that residential users still hot the most data, and drive peaks in usage - which occur as kids came home after school and again after dinner (the old prime-time for television, and now when people hit streaming services most heavily).
"On weekdays, data usage grows slowly until it surges at exactly 3pm and again an 7pm," Rogers said.
"On weekends and public holidays the surge start at 9am."
Earlier, as the new school year started, Rogers said, "When the kids are at school, there's a clear peak at 4pm when they come home, but when they're on holiday, you can see much more consistent use throughout the day. In fact, the biggest difference is at 10am which is nearly 30 per cent higher than when the kids are at school."
Chorus figures for January 2020 showed a 36 per cent increase in data consumption compared with January 2019 as some 385 petabytes was sucked own - equivalent to over a 100 million hours of streaming in HD quality.

Yesterday we had the biggest surge of traffic on the @ChorusNZ network since the RWC. Thought it might be people working from home, but it turns out #CallOfDutywarzone was released at 4am NZT. pic.twitter.com/xFNfSJHrm4
