Rents are rising faster than property values, according to property data firm CoreLogic.
The median amount charged by landlords rose by an average of 6.5 per cent across the country over the 12 months ended July, CoreLogic said.
This was slightly faster than the average rise in property values, which CoreLogic said were up by 6.4 per cent from this time last year.
Growth in median weekly rents by region was lumpy, rising by 14.2 per cent to $297 in Dunedin, but falling 4.3 per cent in Christchurch to $330.
In Auckland median weekly rent was $505, up by 3.5 per cent in the last 12 months.
Rents are up, however, housing activity has slumped - particularly in Auckland and Hamilton.
