(Updates with NZ shares opening after technical glitch)
March 8 (Reuters) - Australian shares slipped at the opening on Wednesday while New Zealand shares opened flat after a technical glitch delayed the start of trading by 90 minutes.
New Zealand's benchmark S&P/NZX 50 index .NZ50 was flat at 7166.64 at 2315 GMT. The S&P/ASX 200 index .AXJO was down 0.26 percent or 15.09 points at 5746.3.
The NZX said it "experienced issues with its trading system and FIX gateway connections" that required a restart of the system, delaying the open. Traders expect lower volumes on the bourse over the day as a result. a summary of overnight action across global markets, double click on AU/CALL
