A minor quakestorm arrived in New Zealand 11 minutes after the Sumatra 6.4.
Local quakes were otherwise quiet.
Solar conditions arrived on cue but were only strong enough to drive equatorial action.

A slight quake pickup may occur late 14 August.

Update. 14 August 11.00pm
14 August.
South of Rotorua 3.6 2.06pm
Local quakes were largely quiet on 14 August.
The biggest quake fitted the forecast location profile but low Magnitude.
A weak solar burst has arrived tonight but may not be enough to drive local quakes.
Very cold air has delivered a slight deluge in Christchurch and a big powder snowfall to Canterbury high country, typical cold wet Little Ice Age weather conditions.

Summary.
13 August.
West of Punakaiki 3.5 3.19pm
14 August.
South of Rotorua 3.6 2.06pm
17 August.
Northern Kahurangi 4.3 8.26am
Quakes went west during the period.
The late addition of rarely forecasted Kahurangi was probably justified.
The 17 August Kahurangi 4.3 came in the following forecast period but by then the location was dropped, a forecasting mistake.
Solar conditions were never strong during the period and New Zealand quakes were largely quiet 15-16 August although other Pacific regions and volcanoes were active.
