The resulting increased supply, alongside signs of a cooling off in demand in China's housing markets, is expected to put downward pressure on prices, ASB Bank rural economist Nathan Penny said.
Latest Ministry for Primary Industries figures for the March quarter showed prices were still elevated - in a range of $171 to $198 a cubic metre (freight on board), having appreciated from a $144 to $153 range since the March quarter of 2012.
The ASB forestry price index, in US dollar terms, peaked in mid-April and has since fallen back by 1.2 per cent.
This came after a 20 per cent rise from the end of 2012 through to mid-April 2014.
"At this stage, they [prices] have flattened and fallen a touch, but we would expect them to come off the boil over the rest of this year because of those issues on the supply side and on that hint of housing weakness in China," Penny said.
ANZ economists said in a market commentary that anecdotes about the state of the Chinese housing market had been grim for some time, but now the problem was starting to show up in official data.
China's new home prices rose in April in the fewest cities for 18 months - 44 of 70 cities tracked by the Government - compared with 56 in March.
Developers continue to offer deep discounts, and some local governments are easing property curbs, the ANZ said in a commentary.
"A property slowdown has long been desired by the authorities, but there is a risk this train could overrun the station," ANZ said.
China home sales fell 18 per cent between March and April, and annual house price inflation is easing rapidly.
"Directing more lending at the sector runs the risk of delaying but worsening the eventual correction, with clear signs of housing oversupply and unsustainably high prices," the bank said. APNZ
