* Polish bonds stronger after supply details
(Updates with Polish cbank, debt supply)

PRAGUE, March 31 (Reuters) - Romania's leu hit a 1-1/2 week low on Wednesday after a central banker said fundamentals did not justify further appreciation, while the Polish zloty held gains when the central bank left interest rates unchanged.
Markets had widely expected Polish policymakers to hold interest rates at a record low 3.5 percent, but are watching Wednesday's statement and news conference for signs they may delay tightening policy more than previously thought.
Weak inflation and strong currencies helped Romania and Hungary cut interest rates to new lows this week, while the Czechs signalled last week that a rate cut was still an option, pushing back market expectations of hikes later this year.
"People are pushing their forecasts (for Polish rate hikes) back to the second half of the year given the currency strength," Nomura economist Peter Attard Montalto said.
"Key for the press conference will be the tone, we expect a neutral bias to remain but with a slightly dovish tone, as well as vote distribution," he added.
The zloty <EURPLN=> rose 0.4 percent on the day to 3.86 per euro, edging back toward a 15-month peak it touched this month but unmoved by the rate decision. Dealers said there was room for more gains.
The Polish bank will hold a news conference and release a statement explaining its interest rate decision at 1300 GMT.
Earlier, bonds firmed after the release of April debt supply, but were unchanged after the rate decision.
LOWER OR ON HOLD
Romania's central bank decided unanimously to cut rates by 50 basis points on Monday, deputy Governor Cristian Popa told reporters on Tuesday, a rarely released detail analysts said likely heralded further easing. [
]On Wednesday he was quoted as saying that current economic fundamentals do not justify firming of the leu. [
]The leu <EURRON=> fell 0.5 percent on the day to 4.09 to the euro by 1111 GMT, its lowest since the start of last week.
"It's verbal intervention," one trader in Bucharest said. "There is pressure (from the belief) that it might be followed by actual intervention."
Dealers said the central bank helped knock the leu off 14-month highs last week, and say the bank intervened last year to check weakening. The central bank has always declined to comment.
Elsewhere, the Czech crown <EURCZK=> and Hungarian forint <EURHUF=> trod water. Hungarian bonds were steady with yields on the 3-year bond around almost 5-year lows and near 2-1/2 year lows on the 10-year. The central bank there has left space open for more monetary easing, which could boost bonds.
The forint also hit its highest level since the turn of 2008/2009 this month, but has retreated around 2 percent since then, while the zloty is only 0.1 percent off its high.
Strategists expect the zloty to outperform peers, which are expected to gain on an export recovery. But analysts warn the path will be choppy with worries persisting in markets over Greece's and other euro zone peripheral countries' debt.
Hungarian and Czech elections this spring will also weigh until new governments are formed and markets assess their strength and policies.
