There's a shallow, slow-slip region near NZ, as opposed to a subduction area that "pulls" the tip on the North Island down about about 5cm/year (Hey, the oceans aren't rising, the islands are sinking!) until it's "released" in an earthquake.
The NZ slow-slip quakes move 10mm-30mm over days, weeks, or months.
Being ocean-shallow, it's probably easier to monitor than the deeper Turkey quakes.
