Not sure if anybody else has there data but would be interesting to compare a few. Every little bit helps when trying to lower the power bill and knowing what uses power is helpful.

Looking at the data, are you on genesis's day/night plan? Depending on where in the country you are, it can make quite big savings.
In Wellington, it's 21.58c for the day (7am-11pm), then, 11.73c for the night vs 23.11c for any time power (so, it's cheaper even if you don't change anything). Everyone should move to this plan - actually, don't, they would then change it.
If you were in Christchurch I think the off peak is from 9pm - (sometime in the morning that I can't remember), so, it's even better value.
Other places have varying differences between the day/night rates and in some places it's not worth it (for my usage).
