The marine sector is warning it's at crisis point - with few superyacht owners booking refits because they can't travel to New Zealand to do them.
Currently the only way to get a foreign vessel here is by booking a $50,000-plus refit.
But just 20 superyachts have done so since rules came into effect last winter.
Now the sector's urging the government to let rich superyacht owners quarantine on board their plush vessels.
Amy Williams and video journalist Dan Cook filed this report.
