The local sharemarket has had its strongest single session in nearly two months.
Tonight's move to level 1 and signs of a lift in activity in major economies have lifted investor sentiment.
The benchmark top 50 index closed up by 352 points, or 3.1 percent, the biggest one- day gain since late April.
Among the biggest rises was Air New Zealand, which gained more than 9 percent on a statement that it should be back in profit in two years.
The market has recouped virtually all the losses incurred since Covid-19 sparked meltdowns in early-to-mid March.
