    didn’t notice the quake but the house creaked somewhat!!! which caught my attention but because I couldn’t detect any earth movement didn’t think much about it! Strange!!!!

    Update: GeoNet has since revised the magnitudes and locations of the onshore quakes to an area about 90 km north-east of Te Araroa.
