@taniwharugby It has really been the cumulative at my place. We've had 500+mm in the past two months.
I still thought the river would have to come up another metre to get my house (and if it managed to do that there would be large parts of Richmond washing up in Wellington).
But, unfortunately, it broke its banks a km upstream - flowed across the plain until it reached the elevated SH6, which it couldn't cross - so it just took the path of least resistance down the side of the road and took out the houses in its path. Looked quite a lot like the footage of the Asian tsunami as it came across the paddock - and a very nasty WTF is that and where's it come from moment.
Any idea on the stopbank construction? I've a feeling it's a bit shit in NZ in general, it's the reason parts of HB got hammered in Gabriel.

@delicatessen Yeah - it went over the top of the stopbank.
To be fair - the river was running at record levels - somewhere around 80-times its normal winter flow.
My house got built in 1860 and to the best of my knowledge the first time it's been flooded - then twice in a fortnight!
The bottom graph is the second major rain event - I think it went over the stopbank at about 350m3/sec.
Most recent rain event was starting to accelerate - another 50mms of rain would have sent it close to that level, because everything was running off.
