At some point someone will have to draw a line to mark the border between an MP acting on behalf of their constituents and an MP acting inappropriately.
Even with just over four months to the election and next week's budget looming, important national issues have taken a back seat lately as the political focus remains fixed on errant MPs.
The ever-evolving Judith Collins affair, punctuated by the fall of Maurice Williamson, means all MPs are under the spotlight, as New Zealand First MP Tracey Martin has discovered.
The Rodney-based list MP wrote to a senior police boss to voice concerns about the possible transfer of a local sergeant who was on the same school board of trustees as her.
Martin wrote a letter to Inspector Scott Webb on her official MP letterhead - but reportedly in her capacity as the chairwoman of the Mahurangi College board of trustees - about the redeployment of a long-serving officer in charge of the Warkworth station.
