A shortage of rental houses, paticularly in Christchurch is fuelling rent rises across the country, according to new figures from Trade Me.
The number of rentals available in the quake-hit region has plummeted 40 per cent in the last year - as the number of inquries to landlords has risen 42 per cent.
"When the first major earthquake struck (in September 2010), we saw supply begin to come under pressure, and the February 2011 earthquake exacerbated the shortage,'' said Brendon Skipper, head of Trade Me Property.
"Supply has continued to plummet, and the current level of rental inventory for the city is the lowest we have seen for years.
"It is a classic case of supply and demand, and is now flowing through to rent. We've seen the average asking rent go up 15 per cent in Christchurch, well ahead of the national increase of 4 per cent.''
