About 40% of the trail was off-road but further fundraising was planned, and there were proposals to expand the off-road section further next year, A2O marketing and sales officer Jason Menard said.
New businesses had already started along the trail, from bike hire and guided tours on the trail to new accommodation providers and new activities.
Already, there were 120 official Alps 2 Ocean partners.
''This is great for our district,'' Mr Menard said.
Tourism operators along the trail had forward bookings.
National cycle trail advocate Prime Minister John Key opened the first part of the trail to be completed - the last 1.3km around the historic precinct and Oamaru Harbour - in May 2010.
The first group completed the whole trail in March 2012 and then earlier this month in Oamaru a ceremony was held to mark the trail being fully sign-posted.
Mr Menard said the major plan for next year was ongoing construction, which would be recorded on the trail website.
At this stage, it was not known how many people had completed the trail but counters were being installed, which would give a clearer picture at the end of this season.
''Warmer months will always see more cyclists on the trail,'' Mr Menard said.
Much positive feedback had been received from many different types of groups who had cycled the trail, particularly about the ever-changing scenery and riding surfaces.
Most of the inquiries about the trail were coming from within New Zealand, but inquiries from off-shore were expected to increase as the marketing plan was developed.
Initially, the trail received $2.75 million in funding from the New Zealand Cycle Trail fund in 2010, but that has already been spent, along with more than another $1.25 million in grants, donations and in-kind work.
Trail supporters, along with the Waitaki and Mackenzie District Councils, would be applying to Mr Key for further funding to take more of the trail off-road, particularly where there were safety issues.
Work was being done to determine what extra funding would be needed and it was hoped to file an application before the end of this month.
