"Having the knowledge that Sarah's still around us in spirit, that helps ease the pain a little, knowing that she still lives on, and that she's still with us."
A website the Carters set up to help record and bring attention to instances similar to their daughter's, ThailandTravelTragedies.com, has been taken down.
"You can only take so much of revisiting the scene of the crime, where all the emotions start to come back too heavily.
"I was finding that I was entering the site with a degree of depression."
Recommendations made in the report such as the establishment of a panel to investigate stricter measures for the use of chemicals in Thailand are now Mr Carter's focus.
This year he plans to contact Thai and New Zealand authorities to make sure the recommendations weren't "lip service".
He has already been given cause for concern - emails sent to the owner of the Downtown Inn, where Sarah fell ill, and the mayor of Chiang Mai have gone unanswered.
"In fact, I haven't even had an apology from either of them. My wife and I haven't had one official apology."
With an increasing number of young Kiwis taking advantage of cheap flights to holiday in the region, Mr Carter says he wants to help shield other families from experiencing what his has.
He declined an offer from TV3's 60 Minutes programme to accompany a reporter to Chiang Mai, "as psychologically I couldn't face going to Thailand".
"But [this] year, if one of the current affairs programmes was going I'd be quite keen on doing a follow-up on exactly what they have done.
"I think that would provide a positive impetus on getting something done."
