* NIB Holdings top gainer on ASX

* Energy index down 2%

* Tech stocks up 1.2%

Nov 4 (Reuters) - Australian shares ended higher on Thursday as gains in banks and tech stocks offset a slide in energy heavyweights, while the U.S. Federal Reserve's plan to taper its bond purchases also boosted sentiment.

The S&P/ASX 200 index rose 0.5% to 7,428 points at the close of trade. The benchmark climbed 0.9% on Wednesday.

Major indexes on Wall Street clocked strong gains after the United States Federal Reserve said it would begin trimming its monthly bond purchases in November, with plans to end them in 2022.

That led the tech stocks to rise 1.2%, with Appen gaining 3.2% to lead gains on the index.

"Currently, investors can be satisfied that the Fed seems to be in no rush to get rid of the policy punch bowl," said Kunal Sawhney, CEO of equities research firm Kalkine Group. He added that changes in the economic outlook could prompt central banks to modify plans.

Gold stocks rose 0.5% on stronger bullion, while financials added 1% as Australia's 'Big Four' banks advanced between 0.2% and 1.4%.

Insurer NIB Holdings led gains on both the benchmark index and financial index, rising 5.8%, as its premium revenue rose in the first quarter.

Investors seemed to shrug off data from the Australian Bureau of Statistics, which showed that the country's retail sales for the third quarter fell 4.4% and also missed a Reuters poll.

"A rebound is now evidently underway, given the high rates of vaccination that is propelling the Australian economy to reopen," Sawhney said.

Energy stocks fell 2%, their worst session in over six weeks, following a slump in oil prices on concerns over increased global supply.

Beach Energy fell 5.2%, while Worley lost 3.2%.

New Zealand's benchmark S&P/NZX 50 index fell 0.4% to finish the session at 12,943.94 points. (Reporting by Tejaswi Marthi in Bengaluru; Editing by Ramakrishnan M.)
