Icebergs to Hit New Zealand?

Nearly 100 icebergs possibly from a partial disintegration of the Ronne Ice Shelf [wiki] six years ago, have approached within about 300 km (186 miles) of New Zealand, with the largest measuring about 1.8 km (1.1 miles) in length and standing some 120 metres (360 feet) above water.

However, according to Mike Williams, an oceanographer of National Institute of Water and Atmospheric Research [wiki], the chance of those icebergs to hit the country is very low:

"It's a natural but a rare phenomenon. It requires a lot of rare occurrences to happen simultaneously. This iceberg has to have managed to make it to the right place in the main currents in the Southern Ocean to have gotten all the way around to New Zealand without melting."

"Then, it has to have moved far enough north to have got pushed up towards New Zealand rather than pushed further south which is what happens to most icebergs."
