(Updates to close)
SYDNEY, April 18 (Reuters) - Australian shares slipped on Monday, hurt by a profit warning from Qantas as well as sliding mining and energy stocks after talks by oil exporters on freezing output collapsed, while New Zealand stocks hit a new record. S&P/ASX 200 index .AXJO fell 20.4 points, or 0.4 percent, to 5,137.1 at the close of trade. After falling 2 percent in calendar 2015, the benchmark has struggled to make back ground, down another 3 percent so far this year.
New Zealand's benchmark S&P/NZX 50 index .NZ50 meanwhile rose 6.5 points, or 0.1 percent, to finish the session at 6,851.2, its fourth record in a row. That index is up 9 percent so far this year.
