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.

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.
