I’ve been watching this since there was renewed seismic activity a few weeks ago, now the volcano is sending up ash.

Information page from the New Zealand’s GeoNet. There’s a webcam link there, but right now it is obscured by clouds.
Interestingly, White Island, which I had the pleasure of visiting back in February, is also showing renewed activity, aside from the usual hydrothermal activity.
