The NZX-50 has recovered almost all the ground it lost during the turmoil that hit global equity markets last week.
The benchmark index yesterday rose above 3276.51 - where it opened last Monday, following Standard & Poor's announcement that it would cut the United States' credit rating, prompting a volatile few days on exchanges around the world - before falling back to close up 0.65 per cent at 3273.75.
The NZX-50 still sits more than 7 per cent below where it was in May.
Grant Williamson, a director at Christchurch sharebrokers Hamilton Hindin Greene, said financial results reported on Monday by exchange operator NZX and courier firm Freightways had buoyed the local market.
"It's been quite a turnaround," he said. "The local results that we have seen so far have been very positive and I think they are bringing a level of confidence back into the marketplace."
