The issue, of course, was brought to our attention, as the Minister said, in September 2018 when the Pohokura pipeline had some leaks and the operator at that point in time needed to investigate that. As part of that process of a planned outage around that remediation and maintenance, there became a further issue around a shut-off valve which extended the inoperability or the limited operability of that field. As the Minister said, the Pohokura gas field, which is offshore of Taranaki, supplies 42 percent of New Zealand's natural gas, and this became a significant issue that affected not only the spot price of gas, but also the spot price of electricity for an extended period of time, which I'm sure I'm not going to be able to talk about for much longer as we hit 10 o'clock at night.
