Jan 23 (Reuters) - Australian shares extended gains on Tuesday, driven by miners and financial stocks, as a survey showed that business confidence in the country improved last month, while technology stocks continued to track a Wall Street rally.

The S&P/ASX 200 index jumped 0.5% to 7,514.90 points, its highest closing level in two weeks, and marked its third straight daily rise.

The S&P 500 ended at its all-time closing high for a second straight session, as technology firms added to recent gains.

Locally, a survey from National Australia Bank showed its measure of business confidence rebounded 7 points to -1 last month.

"Gains today came courtesy of supportive tailwinds from Wall Street and as the NAB Business confidence index improved in December from the prior month," said Tony Sycamore, a market analyst at IG Australia.

Heavyweight financials rose 0.8%, ending at their highest level since late-April 2022, and recording their fourth straight daily gain.

The 'big four' banks firmed between 0.5% and 1%, while top lender Commonwealth Bank of Australia ended at its record closing high.

Miners climbed 0.6% in their best day in two weeks, following a rise in iron ore prices after top steel producer China pledged to support market confidence.

Sector giants BHP and Fortescue rose 1% and 0.8%, respectively.

Information technology stocks also extended their rally, rising 0.6% on a positive lead from their Wall Street peers.

Index major Wisetech Global rose 2.7%, having hit its highest level since August during the session, before paring gains.

Healthcare companies climbed 1%, rising for a third consecutive day to end at a seven-month high, with Healius and Ramsay Health Care gaining 2.6% and 1.2%.

Bucking the trend, gold stocks lost 0.7%, with Northern Star Resources and Evolution Mining dropping 2% and 2.2%, respectively.

Across the Tasman Sea, New Zealand's benchmark S&P/NZX 50 index finished about 1% higher at 11,802.88 points. (Reporting by Aaditya Govind Rao and Sneha Kumar in Bengaluru; Editing by Mrigank Dhaniwala)
