That followed a long public submissions process but went only part way to satisfying a call from iwi and others to keep all traffic off the entire mountain "so it's been a huge disappointment that the management plan hasn't been implemented".
Bus and coach operators say the Auckland Council dropped a bombshell on them early last week in telling them that heavy vehicles would be banned from the summit from late next month.
After a heated meeting, the council agreed to delay the start of the ban until December 12, but the operators want an extension until at least April to ensure the itineraries of cruise ship passengers are not disrupted.
Council parks, sports and recreation manager Ian Maxwell said that after speaking to iwi and local community members, his team decided that delaying the move until December "was about as far as we could go".
He expected many people would be prepared to walk from halfway up the mountain to the summit, but the council intended providing a free shuttle service for elderly people and others who may not feel up to the challenge.
Mr Maxwell said coaches trundling up the summit's narrow and largely one-way road were becoming larger and posing hazards for pedestrians as well as putting pressure on the mountain's erodible slopes.
Albert Eden Local Board chairman Peter Haynes said it was nonsense for coach operators to claim that tourists would be barred from the summit, and noted that the former restaurant halfway up the mountain had been turned into a visitor centre.
But Inbound Tour Operators' Council chief executive Lesley Immink said the Auckland Council had produced no evidence of damage or accidents caused by coaches on the mountain and the ban would force her members to remove it from their itineraries.
She said coaches carried almost half of the 1.2 million people who visited the summit annually, and most of their passengers were elderly people who would not be up to the climb.
They would require a fleet of shuttles, but the coach operators could not afford the extra time that would take.
Ms Immink feared the operators would be penalised for not providing the spectacular views of Auckland from the summit which they had promised overseas visitors in brochures.
