The Herald reported earlier this week that Chris Pilone, the man who mentored Hamish Carter to Olympic glory at Athens in 2004, is likely to become Hewitt's coach until the Rio Games. Pilone has had a successful career coaching elite athletes across the athletics, triathlon and boardsailing disciplines. Hewitt's former coach Dr John Hellemans is expected to assist in a background capacity.
Hewitt was the first New Zealand athlete selected for the 2016 Olympics.
She met the Olympic Committee criteria with three World Triathlon Series podium finishes, the first occurring in the 2014 grand final in Edmonton, followed by bronze medals in Auckland and Stockholm this year.
The 33-year-old backed up those results with fourth at the Chicago grand final and the overall world series silver medal, the fifth time in seven seasons she finished ranked in the world's top three.
Hewitt raced eight International Triathlon Union elite events this season. She secured two podium finishes but always finished inside the top eight. She did not finish the Olympic test event in Rio.
Hewitt's selection is conditional on New Zealand receiving a quota spot, which should be confirmed in May.
Maw said Hewitt did convey her thanks to the wider sporting community and media back home for their support.
"Andrea will speak in her own time but has asked that Tri NZ passes on her thanks for the support and messages received over the past few weeks, messages that were heartfelt and warmly received by both Andrea and Laurent's family in France.
"For now Andrea must be left to return home and spend the holiday season with her family and friends and go about putting together her Rio campaign without intrusion or speculation. Tri NZ will continue to support her in every way possible."
