Also stolen in that burglary were a distinctive steel-sided trailer and six karts used for the club's Have A GoKarts introduction programme.
Mr Potaka said the carts were among several "bigger-ticket" items of machinery and trailer items stolen in the Hastings area in recent months and still missing.
Among them was a 1.7 tonne Yanmar digger stolen along with a truck last week from a yard off Johnston Way, Whakatu.
Discovered missing on July 21, the yellow digger is still missing, as is a range of tools, but the Isuzu truck was found that day abandoned on a riverbank off State Highway 50 near Tikokino.
Both the truck and the digger had Unison company branding.
Also still missing are a chiller and trailer stolen from Havelock North in May, and a yellow and red home-made mini car stolen in March.
Mr Potaka said the go-kart raids were particularly distressing, and there must have been suspicious activity relating to them, and the other incidents.
?Suspicious movements should be reported to the police at any station, by phone on 8310700 or anonymously on Crimestoppers ph 0800 555 111.
