(Updates to close)
SYDNEY Aug 21 Australian shares added 0.1 percent to close at a fresh six-year high, though a disappointing survey on Chinese manufacturing took much of the shine off a handful of strong earnings reports and Wall Street's upbeat performance.
The S&P/ASX 200 index added 4.3 points to 5,638.9 at the close of trade after earlier hitting an intraday high of 5,679.5. The benchmark rose for a sixth consecutive session, its longest winning streak since mid-July.
New Zealand's benchmark NZX 50 index added 0.2 percent or 12.6 points to 5,152.9. (Reporting by Thuy Ong; Editing by Jeremy Laurence)
