Whangarei Barfoot and Thompson branch manager Martin Dear said many of the company's recent sales had been high-value properties.
There had been lower-priced sales, he said, but just not as many.
"It's like the first-home buyers aren't around and aren't as strong."
The number of Whangarei February sales, 59, was quite low, he said.
"It must be relative to the cheaper houses not selling so much."
Buyers for higher-priced properties were coming from Auckland and Hamilton which was "really encouraging".
Generally the market had improved and auction sales were going well.
However, only investors were really buying cheaper properties, he said.
Meanwhile, new monthly figures from the Real Estate Institute of New Zealand show the median house price for Northland jumped 11.1 per cent during February to $344,500 - up 2.8 per cent from the corresponding month last year.
The number of sales jumped 24.1 per cent to 175 last month - an 11.5 per cent year-on-year lift.
The national median price rose $33,000 to $415,000 compared to last February and was up $13,000 or 3.2 per cent on January this year.
REINZ chief executive Helen O'Sullivan said the Northland market continued to perform well, with rising numbers of sales year-on-year compared to the rest of the country.
"Vendors are increasing their price expectations, but that is not having a negative impact on the market as yet."
