He said there was activity in most suburbs and the average sales price was up on the average valuation.
First-home buyers were active and investors were tightening up a bit as a result of new investment rules, said Mr Kubiak.
"We've got Aucklanders coming down here looking around.
"We've got people from Whangaparaoa, Hamilton, Auckland, Wellington, Christchurch, so it's a good sign."
Mr Kubiak said summer was typically a busy time in real estate and winter quiet.
"Winter was extremely busy ... We'll be straight back into it in January, I guarantee it."
Tim Hocquard, principal of Ray White Real Estate in Whanganui, said things were very upbeat, with more higher-value properties selling than before.
"So there's people coming to Whanganui prepared to buy a house at what we think in Whanganui is a very good price," he said.
He said a number of low-priced properties were bringing the median value down.
Local people, rather than absentee owners, were buying investment properties. These local investors were more inclined to ensure their properties were well looked after. Mr Hocquard expected many people to list their homes for sale in January, particularly those keen on upgrading.
"People make decisions over Christmas and New Year, life-changing decisions - we're expecting people to list their properties."
There would be plenty of buyers to snap those up.
"Some had missed out on properties in the past and were more prepared and ready to buy.
"So our market is changing a lot. We're certainly nowhere near as urgent as some of these bigger city markets but buyers are prepared to buy houses," he said.
Median house prices and sales volumes grew across New Zealand during November, according to REINZ.
Its figures showed 10 of 12 regions in New Zealand hit in November 2016, with the national median price also reaching a new mark of $520,000.
Only Auckland and Central Otago Lakes did not post record median prices.
The number of sales this November was 7576, an increase of 13 per cent on October. Sales volumes fell 6 per cent compared with November 2015.
The latest E-Valuer quarterly property report from qv.co.nz illustrates the rising value of real estate in Whanganui.
The figures show the median value of property in each suburb, with everywhere in Whanganui showing double-digit gains over the 12 months to September 2016 - Aramoho and Castlecliff being the big winners.
