Justice Timothy Brewer told Carson that normally people in her position are sent to jail after pleading guilty but said it was important she continue to get help.
"It's important because you need to front up to the sentencing judge with as much of a hopeful picture as you can create."
Police have records of conversations between Carson and another woman that show she bought a litre of liquid fantasy for $9500.
The deal was done in October last year, according to the summary of facts read out in court.
Carson arranged for a man to pick up the fantasy and arranged for him to get an unknown amount of methamphetamine to sweeten the deal and ensure her drugs was not tampered with.
But Carson had come to the attention of the specialist police group known as Organised and Financial Crime Agency New Zealand and the Customs service.
Twelve packages addressed to Carson or her alias Vic Mare were intercepted at the Auckland International Mail Centre between April and October last year.
When the packages failed to show up to her Herekino home in the Far North, Carson asked a friend if she could have the packages addressed to the friend in future.
Police also have records of that conversation. According to the police summary, Carson's friend suspected Customs may have stopped the packages getting through.
According to police, the packages came through the Royal Mail service and originated in the United Kingdom. Police say in total Carson arranged to receive more than 2kg of the drug.
She is due to be sentenced in August.
