28 March. East northeast of D'Urville Island 3.9, North of East Cape 4.1, Northwest Arm Te Anau 4.2, Upper Arawhata River 4.5
The forecast period is extended to 29 March.
Quakes could be quieter on 29 March before increasing again.
Two near perfect location hits to match the two hits from the 15-17 March period.
The remote Upper Arawhata 4.5 went mostly unnoticed and just a couple days hike over the Olivine Range from the Hollyford River target zone.
The addition of Cook Strait was justified. The forecast map now shows Northern Cook Strait and the East of D'Urville 3.9 was nearby.

Update. 29 March 2300NZST.
29 March. Mt Arthur 3.9
Action eased today as expected.
Quakes are busy but at lower magnitudes.
The Mt Arthur 3.9 near Motueka was very deep and not felt at the surface.
