The lowest terrace at Orakei Korako is the jade-green Emerald Terrace, the largest of its kind in New Zealand since the presumed destruction of the famed Pink and White Terraces in the Mount Tarawera eruption of 1886. However, researchers recently rediscovered the Pink and White Terrace locations. In peak wet conditions up to 20 million litres of silica-enriched water per day may flow over the terrace and into Lake Ohakuri.
