BEIJING, July 15 (Reuters) - Growth in China's new home prices in June was flat after a dip in May as widespread COVID lockdowns were relaxed and consumers took advantage of a slew of stimulus measures such as cuts in mortgage rates and smaller down payments.

Average new home prices in 70 major cities remained unchanged month-on-month, after a 0.1% drop in May, according to Reuters calculations based on National Bureau of Statistics (NBS) data released on Friday.

From a year earlier, new home prices in June fell 0.5% after a 0.1% drop in May.

China's property market, a pillar of economic growth, is mired in a deep slump but recently began to show some signs of improvement after authorities implemented hundreds of stimulus measures aimed at home buyers this year.
