"There has been a growing trend of Aucklanders selling up and moving north in search of more affordable properties in locations such as Whangarei and Kerikeri and this trend is continuing."
He observed that values had also continued to rise in northern parts of the Auckland region such as Rodney.
Martin Dear of Barfoot and Thompson Whangarei said it was a "great market" at the moment.
"We're still seeing a lot of buyers coming in from out of town.
"I also think it's a lack of listings."
In the Far North, the average house cost more than $400,000. Prices have risen by just over 16 per cent in the last 12 months.
QV spokeswoman Andrea Rush said the growth in value in the regions was driven by buyers from the main centres.
"Values in regional centres such as the Kaipara District, the Hawkes Bay, Nelson and the Tasman District are now seeing stronger value growth than the main centres as buyers look to the regions in search of more affordable homes."
Paul Beazley of LJ Hooker Whangarei said a mixture of people are buying houses in the city.
"Auckland buyers definitely have influence, so do first home buyers.
"Investors are still around - it's easier to buy a house with a 40 per cent deposit in Whangarei than it is in Auckland."
Ms Rush said the need for high deposits was slowing growth in property prices at a national level and particularly in Auckland.
"High prices coupled with banks' stricter lending criteria are making it increasingly difficult for anyone but cash buyers or those with higher levels of equity to buy property."
Values across Auckland have had zero growth over the last three months, although growth remained at 7.2 per cent over the year to June.
The average home value in Auckland remained at $1,045,059. In some parts of Auckland, they decreased in the last three months.
Values also fell in parts of Christchurch, although in Wellington growth continued.
The average value in Wellington, the second highest in the country, remains well below Auckland levels at $609,552.
Mr Dear said he was seeing buyers from a range of places, although local buyers still made up the bulk of the market.
"The main reason is affordability . . . I still think we're undervalued."
Mr Steele said growth in Northland was dependent on what happened in the rest of the country.
"If things continue to slow down in Auckland and confidence in the wider market begins to fall, this easing in the rate of value growth could also follow further north."
Nationally, values have risen by 8.1 per cent over the year and 1.2 per cent in the last three months.
The average house value across New Zealand was $639,051.
