The declaration was made at 11.30am on September 8, 2011, recorded in an email sent a day before Drinnan revealed it in his weekly media column. On September 9, 2011, Drinnan reported: "Brewer says he declared the trip as a gift."
Drinnan said he called Mr Brewer either the day before the column ran or two days before.
Mr Brewer said a September 7, 2011, email from council electoral officer Bruce Thomas alerted him to the need to declare the trip. The email was sent to all councillors to alert them of the need to declare gifts worth more than $300 ahead of the Rugby World Cup.
He said he wasn't sure when Drinnan rang but accepts "Drinnan might have come between those emails. I don't know."
Mr Brewer said he was among members who had not filed a complete return of interests and had made a $1000 donation to the city mission. He also called for the debate to be focused again on Mr Brown. He said Mr Brown had declared no gifts.
Code doesn't apply
Mayor Len Brown is a justice of the peace - a group considered to uphold the highest ethical standards.
But those standards don't apply to Mr Brown, according to the Royal Federation of New Zealand Justices.
Federation registrar Alan Hart JP said a small number of emails had been received taking issue with Mr Brown's role as a JP, which he is automatically granted as mayor of a local body.
Mr Hart said that JPs appointed as a result of their roles werenot covered by the federation's rules, including its code of conduct.
