"It is the first time that New Zealand has ever hosted the BMX world championships and that is going to be very exciting for our sport. With it being staged at the Vector Arena it is also a superb opportunity for us to profile the sport at the highest level to New Zealanders.
"At the same time we are looking for riders that have the ability to contribute towards securing Olympic qualifying places for 2016 and the ability to win a medal in Rio. For some of the riders the next 18 months will be spent developing towards that objective."
London Olympian Kurt Pickard (Tauranga) has retained his place in the team along with Matt Cameron (New Plymouth) and Daniel Franks (Christchurch). The newcomers include Kaiapoi's Trent Jones, up from the junior ranks, and Trent Woodcock (Pukekohe), who was a double junior world championship medallist two years ago.
Walker will be joined by New Plymouth's Victoria Hill in the elite women's team, with the Taranaki rider dominating the weekend competition. She also competed in last year's world championships in Birmingham.
The team members who are part of BikeNZ's high performance unit will complete a training camp next week with combinations to compete at the Oceania championships in Brisbane next month and six weeks of racing in the US in June and early July. That group will complete a final training camp in Brisbane before the world championships.
The Challenge (age group) team will be confirmed later this week.
