Whilst the formation of a Cyclone in this position has been predicted in the models for a long time, its formation is uncertain until it happens, and a critical point in the unfolding story of this #KiwiDeluge.
In this animation you can see the circulation form and its size.

Towards the end of the animation you can also see that it has started to move south eastwards, also as predicted.

Here's a broader view showing all of NZ and the cause of the rain converging atmospheric rivers coming together over the Tasman Sea and bringing a continuous stream of thunderstorms towards the Southern Alps.
Here's your problem Kiwis. A persistent atmospheric river running for the next 111 hours across most of the country.
And after that you may or may not get hit by a moisture laden Northerly Storm/Cyclone.
