New Zealand made a 400-plus score for the first time in one-day cricket as they thrashed Ireland by 290 runs in one of the most one-sided matches ever.
Brendon McCullum (166) was at one point on course for the first double-ton in ODIs as he and James Marshall (161) added 274 for the first wicket.
That shattered New Zealand's previous best for a partnership in one-dayers.
Ireland, needing 403, were bowled out for 112 for the biggest loss ever by a side chasing in one-day internationals.
Ireland had key players missing through injuries and county commitments, and were barely recognisable from the team that had caused such a stir at the 2007 World Cup.
ODI PARTNERSHIP RECORDS
By contrast, New Zealand were on a roll after winning the last three one-day internationals in England, and arrived in Scotland with confidence high.
Ireland won the toss at the first ever ODI at Aberdeen's Mannofield Park and elected to bowl first but had to wait until the 43rd over to take a wicket.
McCullum, having hit 10 sixes and 11 fours, holed out attempting one shot too many, but the carnage continued over the closing overs through Marshall and Ross Taylor, who hit 59 from 24 balls.
New Zealand finished with 402-2, the sixth best score ever in ODIs.
But Ireland's chase went reasonably well until the fifth over when the first wicket fell with the score on 29.
Tim Southee and Michael Mason struck regularly from then on, and only some brave hitting from number 10 Peter Connell (22 not out) prevented an even more embarrassing result.
606: DEBATE
Ireland skipper Kyle McCallan, one of just three survivors from the World Cup squad, said: "That was humiliating.
"New Zealand showed they are top side with class batsmen but we set ourselves targets with the bat and fell far short of what we want.
"The guys have to take a close look at themselves and I'm sure they are all as embarrassed as I am.
"We have to regroup for tomorrow [when they take on Scotland].
"They are a similar side to ourselves and we will be under big pressure to put on a much improved performance."
