Foreign buyers have dominated 2018's commercial property deals, which are predicted to exceed $10 billion by year's end.
Chris Dibble, Colliers International's research and communications director, said latest analysis showed total sales were on track to crack through $10b in 2018 and could reach a record.
Nine of this year's top 10 deals had buyers with strong overseas ties, he said.
That's partly because New Zealand's cheap, Dibble said.
"Their motivation is primarily centred on the relative value of our properties when compared internationally. Competition for quality assets globally has ramped up and large global funds are scouring the world for opportunities. New Zealand has a lot of favourable attributes when it comes to investing in commercial and industrial property," Dibble said.
