The focus on long-term focus on capital growth was even more evident with the five-year trend in rents showing a rise of just $50 per week from a median weekly rent of $350 in December 2009, to $400 per week in December last year - up 14.3 per cent, Mr Jefferies said.
Trends in rents across many regions were equally moderate.
Auckland has ended the year at the same weekly level as a year ago, with a median asking rent of $450 per week.
Of the major metro areas, only Wellington and Christchurch saw increases through last year, with median weekly rents up 3.9 per cent and 4.8 per cent respectively.
Only two of the fifteen regions showed double-digit growth for the year with the Bay of Plenty median asking rents up 13 per cent to $340 per week, and Taranaki up just under 13 per cent to $350 per week.
In contrast, only two regions showed falls in rents with Manawatu/Wanganui median asking rents down 4 per cent to $230 per week and the West Coast down nearly 6 per cent to $250 per week.
Mr Jefferies said "the heart of the rental market" was medium-sized homes of three or four bedrooms.
"These are the most sought after by tenants and continue to be the driver of rental prices across the country's three major metro markets."
