Questions remain over Meka Whaitiri's correspondence with Speaker Adrian Rurawhe, before she defected from Labour.
The Speaker isn't budging on making Whaitiri an Independent MP - and not invoking the waka jumping legislation.
He won't release his correspondence with Whaitiri, saying it's privileged.
ZB's senior political correspondent Barry Soper says that doesn't pass the sniff test.
"He's hiding behind the confidentiality that he says he must maintain when dealing with MPs. This is different than the normal chit-chat though between an MP and the Speaker, this is a confidentiality issue."
