The median asking rents for rental homes throughout the country advertised on Trade Me Property rose by 7.1% last year, but there were big differences in different parts of the country.
In Auckland, the country's biggest rental market by far, the median rent was up just 3% for the year, and in the month of December the median weekly rent was $510, which was down $10 a week compared to November.
Christchurch remains a renters' market and asking rents in December were down 5% compared to a year earlier, while in the whole of Canterbury the median rent was down 2.5% for the year.
Trade Me said asking rents in Christchurch had been stagnant for around 18 months and December's median asking rent of $399 a week was still well below the peak of $495 achieved in March 2015.
"Unlike Auckland and Wellington, Christchurch tenants are in the box seat. Rents are barely moving and there are plenty of options in the market," Trade Me's Head of Property Nigel Jeffries said.
Of the major centres, the Wellington region posted the biggest gain in rents, where they were up 9.8% in December compared to a year earlier.
