Greater resources for the taxman to investigate property deals are being considered as part of this year's budget, Finance Minister Bill English says.
Mr English told reporters this morning that he did not agree with the Reserve Bank's recent comment that property speculation was pushing up house prices in Auckland.
But he said there was an ongoing discussion about whether the Inland Revenue Department could be doing more to enforce current laws around property speculation.
There was already a tax in place for people who bought property with the intention of reselling it, Mr English said.
And with real estate agents and buyers reporting high levels of trading activity in Auckland, "there is a question of whether that should give rise to further enforcement activity".
