SYDNEY, March 31 (Reuters) - The yen stayed on the defensive early on Monday, reaching a fresh six-year low on the New Zealand dollar as demand for the safe-haven currency waned amid hopes of more stimulus from China.
The dollar traded at 102.87 yen, not far from Friday's one-week peak of 102.98, while the euro briefly touched a one-week high of 141.74. The kiwi rose as far as 89.23 yen, a level not seen since November 2007.
Traders said China's official manufacturing PMI survey due on Tuesday will be closely watched after a recent string of disappointing data pointed to a slowdown in the world's second biggest economy.
"We expect a decline to 49.8 in March from 50.2 in February, falling below 50 for the first time in 17 months, as growth momentum continues to fade. This should further heighten the urgency to ease policy," analysts at Nomura wrote in a note to clients.
Investors will also be keeping a close eye on euro zone inflation figures due later on Monday after data late last week showed a key measure of German inflation unexpectedly slowed in March.
The soft reading raises the downside risk for euro zone inflation, which is set to stay in what European Central Bank (ECB) President Mario Draghi has called the "danger zone" of below 1 percent for a sixth month.
Yet, Bundesbank President Jens Weidmann on Saturday said the ECB should not over-react to the slowdown in inflation as it was caused largely by temporary cyclical factors.
In any case, traders said a weak number will no doubt put the ECB under more pressure to act and that would be negative for the euro.
The common currency last traded at $1.3747, having plumbed a one-month low of $1.3704 on Friday.
In contrast, commodity currencies such as the Australian and New Zealand dollars have been riding high on prospects of more stimulus from China.
The Aussie scaled a four-month peak just shy of 93 U.S. cents last Friday, while its Antipodean counterpart hit a 2-1/2 year high near 87 U.S. cents.
The kiwi, further supported by the likelihood of more interest rate hikes at home, appeared on track to retest its post-float peak of $0.8842 set in late 2011.
