* Kiwi and Aussie give up earlier gains made on strong data
* ECB's Trichet awaited for comments on slowing euro zone

TOKYO, Aug 7 (Reuters) - The dollar fell from a seven-month high against the yen on Thursday, a day after the U.S. currency rallied as a fall in oil prices to a new three-month low eased concerns about the drag of high energy prices on the world's biggest economy.
The New Zealand and Australian dollars gave up earlier gains against the dollar after strong employment data did little to alter expectations that the central banks there will cut interest rates in the coming months.
Traders said investors booked profits following the U.S. dollar's rally the previous day as oil's retreat below $120 a barrel helped Wall Street shares on Wednesday. [
]The market had digested a hefty amount of dollar offers from Japanese exporters below 109 yen, not expecting aggressive dollar selling from them in the short term.
"The dollar is clearly on a rising trend against the yen," said Tsutomu Soma, a senior manager of foreign assets at Okasan Securities.
"Growing concerns the Japanese economy might be in a recession should also help buoy the U.S. currency," he said.
The yen was under pressure after a series of data supported the view that Japan's longest expansion of the postwar period may be over, reinforcing expectations that the Bank of Japan will keep interest rates at 0.5 percent for a while.
The dollar fell 0.1 percent from late New York trade to 109.57 yen <JPY=>. It had hit a seven-month high of 109.89 yen on trading platform EBS the previous day.
The market was watching to see if the U.S. currency would rise above a technical resistance point at 109.95 yen -- a mid-point between a 13-year low of 95.77 yen struck in March and last year's peak of 124.14 yen, the highest since December 2002.
The dollar index, which measures the currency's performance against a basket of six currencies, fell 0.2 percent to 74.184 <.DXY>, down from a two-month peak of 74.307 hit the previous day. The index closed above the 200-day moving average on Wednesday for the first time since April 2006.
The euro edged up 0.1 percent to $1.5431 <EUR=> ahead of a policy meeting on Thursday at which the European Central Bank is widely seen leaving interest rates unchanged at 4.25 percent. [
]The focal point in the market will be comments by ECB President Jean-Claude Trichet on the euro zone economy.
"Trichet has little choice but to admit that euro zone growth is slowing," said Hideki Hayashi, chief economist at Shinko Securities.
Analysts said cautious remarks about the euro zone economy from Trichet would impact the euro more and bring the currency lower, while the ECB chief is expected to growl again at record inflation in the region and keep a neutral stance on monetary policy. [
]The New Zealand dollar was nearly flat at $0.7172 <NZD=D4> after government data showed on Thursday that employment rose much more than expected in the second quarter, sending the kiwi to the day's high of $0.7219 at one point.[
]The Australian dollar was up 0.1 percent at $0.9098 <AUD=D4>, retreating from earlier highs around $0.9130 hit after data showed net employment increased by 10,900 in July, surprising economists who had forecast a gain of only 1,250. [
]The Aussie had hit a four-month trough of $0.9065 on Wednesday after the Australian central bank kept interest rates steady but opened the door to lower rates.
Sterling was little changed at $1.9480 <GBP=D2>, staying near a seven-week low of $1.9467 reached the previous day, as investors waited for the Bank of England to deliver its latest interest rate decision later in the day.
The BoE is expected to keep rates on hold at 5 percent as it is caught between strong inflationary pressures and the need to guard against deteriorating growth, like many other major central banks. [
