Prime Minister John Key has rejected calls by Labour to stand down a minister whose brother is facing indecency charges.
Mr Key said the minister informed him on April 1 about the charges and offered to stand down.
The Prime Minister sought advice from the Cabinet Office as to whether a conflict of interest existed.
He said "further, deeper advice" was sought by the Cabinet Office and that advice confirmed there was no conflict of interest.
He would not say where the further advice came from but it could have been from the Solicitor General, a QC, an academic or another specialist in such matters. "I am quite confident the position is correctly assessed and thorough," Mr Key said.
