UPDATE AS FOLLOWS

There areas under the National Advisory and experiencing strong and unusual currents have reduced.

The West Coast of the South Island, and Cook Strait, meet the threshold for the National Advisory to remain in place however, the tsunami activity threat is at the low end of the scale.

Strong and unusual currents on the eastern side of New Zealand may be present for another 24 hours.

The next update is expected around 7.30pm this evening, and these areas will be reviewed and updated at this time.
