Dunedin's property values are going against the norm, according to this month's QV residential property index survey.

Unlike many of the main centres, Dunedin's property values haven't consistently decreased, with the past month showing a 1% growth in the gap between higher and lower values.

Auckland and Wellington prices have slipped slightly over the past year, nearly 1% and almost 2% respectively.

Hamilton and Tauranga values have been relatively static for most of the year, showing no significant increase in the second half of 2009.
