SYDNEY/WELLINGTON, July 8 (Reuters) - Australian shares slipped 0.2 percent on Tuesday, pressured by big name banks as Wall Street fell overnight, while a drop in metal and oil prices constrained resource sector stocks.

The NAB Business Confidence index hit the highest level in five months in June, though that “failed to spark much buying interest,” William Leys, sales trader at CMC Markets, said in a note.
He said the pending U.S. earnings season “has prompted buying caution as full valuations mean expectations are high.”
U.S. stocks on Monday retreated from last week’s record level on hesitancy to make big bets before earnings season.

The New Zealand share market was softer but with no particular driving force with the benchmark NZX-50 index was 14.77 points or 0.29 percent lower at 5,171.59.
Retirement village operator Summerset Ltd was down 2.1 percent at NZ$3.30, and software company Xero Ltd was off 1.9 percent to NZ$26.00.
