Video: Trampers flee as Mt Tongariro erupts
A Napier school trip turned unexpectedly dramatic today when Mt Tongariro erupted.
Up to 90 Napier schoolchildren were on the mountain, two hours into a tramp on the Tongariro track.
Tamatea Intermediate teacher Lomi Schaumkel said the group - which also included six parents and four teachers - was near the Katetahi hot springs when they saw the beginnings of the eruption.
School staff captured this footage.
