The median cost of rent in Wellington has soared to a record $480 per week, according to latest Trade Me data.
Rents in the capital for January were up 6.8 per cent on last year, with tenants being asked to fork out an extra $1500 per year for a typical rental property.
Head of Trade Me Property Nigel Jeffries said a sharp dip in the number of properties available was exacerbating the issue.
One Wellington flat received almost 100 inquiries within hours of being listed, and 350 in a week, he said.
"Over the past year the pressure of demand overtaking supply has seen the number of rental properties decline by over 70 per cent."
