Mr Robertson said some 2000 of the 14,000 ratepayers owed the council about $6 million in unpaid rates from as far back as three years.
"I'll be putting out messages to encourage people that are holding back to pay because the court has made it absolutely clear that they are valid rates therefore they should be paid.
"For some, there's been uncertainty [on rates] because of the judicial review and the campaign by the MRRA [association] encouraging people not to pay has been quite strong over the years but I'd expect them to re-consider their stand now and to pay up," he said.
Mr Robertson said the council was servicing its debts, including loan repayment for the sewerage scheme, properly.
But association chairman Bruce Rogan said his members would stay put.
"We won't recommend payment of any dollar to this council until we get disclosure from them on how they'll deal with the council debt."
Mr Rogan said the council had cruelly levied penalty on rates that were then illegal but were now legal after the court judgment.
