Barry Soper: Newstalk ZB senior political correspondent on Speaker Gerry Brownlee incorrectly declaring his property ownership for two decades - Heather du Plessis-Allan Drive

Our newsroom can reveal Parliament's Speaker's been filing incorrect property declarations for the past two decades. 

Gerry Brownlee last year amended 15 of his 19 pecuniary interests declarations, dating to 2005. 

But some changes still appear to be incorrect. 

The inconsistencies stemmed from failing to declare a property entirely - and even declaring one he didn't own.

Newstalk ZB senior political correspondent Barry Soper explained further, and revealed whether Kiwis should be concerned.
