Please note the change to our Sample Reception hours for non-statutory days.  From 4pm onwards please place samples in the Afterhours box and move the slider from blue to red.

GMP Chemistry Nelson & Auckland Laboratories
The lab will be closed from Monday 23 December 2024, reopening on Monday 6 January 2025.  Samples will be accepted over the holiday period in Nelson, but TAT’s may be extended due to closure.

Food Chemistry Laboratory (Including Trace Metals)
The lab will be working with a skeleton staff for non-statutory days and closed at weekends.

Natural Toxins
The biotoxin and phytoplankton labs will be open on the non-statuary days and closed on the weekends.

On open days, samples need to be received at the lab before 10:00 am to ensure they are processed that day.  Phytoplankton results will be reported the same day and biotoxin results reported the following working day.  Samples received after 10 am for biotoxin testing will be added to the next run.

Shellfish samples received Friday (27 December and 3 January) may have to be reported the following week, dependent on the sample numbers received. To increase the chances of having results reported before the weekend, please send samples to the lab as early in the week as possible.

Courier Services
If you plan to send us perishable/time sensitive samples for testing, we recommend that the following two dates are the last you use to ensure delivery:

• Prior to Christmas: Monday 23 December 2024
• Prior to New Year: Monday 30 December 2024
