There's one foolproof way for Prime Minister John Key to avoid accusations of lying about having contact with Whale Oil blogger Cameron Slater - have no communications with the man.
You would think that with the stench of Dirty Politics still lingering in the corridors of power after this year's madcap election build-up, Mr Key would know better than to conduct a text conversation with the figure at the centre of the controversy.
Mr Key, who gave Mr Slater his new cellphone number after he changed it during the election campaign, says he is "fundamentally not" in contact with Mr Slater, and hadn't rung him or "proactively texted" him.
Though according to at least one report he also said he phoned Mr Slater on Wednesday to confirm his recollection of what they discussed in their text exchange on Monday night as he'd deleted the texts.
On Wednesday night he had to back down on his earlier claims he'd had no contact with Mr Slater ahead of the release of Inspector-General of Intelligence and Security Cheryl Gwyn's report into the SIS's role in Slater's 2011 political attack on former Labour leader Phil Goff.
