The course of dealings between the parties
16Following the agreement reached during the telephone conversation or at the meeting, ARC Holdings and then, when Mr Evans and his wife acquired the shares in Colyer Fehr, Colyer Fehr began to purchase tallow for KNZA. The basic pattern of how that occurred appears to have been established almost immediately and to have continued until the relationship terminated in 2006. Although the tallow was acquired on behalf of KNZA, Mr Evans received all his instructions from Kerry - principally, Mr Jones, until Mr Jones left Kerry in 2002. From about that time, Mr Evans Jnr took over his father's role and he dealt principally with Mr Spence. Generally, for tallow bought for KNZA, the invoices were made out in the name of KNZA and were sent directly to KNZA for payment or were forwarded for payment to KNZA by ARC Holdings and, subsequently, Colyer Fehr. Because of the close relationship between the parties, they were often confused. Consequently, KNZA was sometimes referred to as Colyer Fehr and, as I shall explain, sometimes invoices intended for Colyer Fehr were sent to KNZA by mistake. Colyer Fehr would also use KNZA's letterhead when negotiating or issuing instructions to third parties on KNZA's behalf.
17Mr Evans Snr and Mr Jones, and later Mr Evans Jnr and Mr Spence, spoke frequently to discuss the general state of the market, the bids that would be lodged on behalf of KNZA, shipping schedules and trading and stock management strategy. Mr Evans Snr estimates that he or Mr Evans Jnr spoke to representatives of Kerry and KNZA on average about 10 times per day. Those discussions took place against the background of a number of documents prepared by the parties. One type of document was a weekly shipping sheet prepared by Kerry summarising the quantities of tallow that it required to meet contracts that it had entered into with its overseas customers, the quality of tallow required and the port from which it would be shipped.
18Another type of document, prepared by ARC Holdings, and subsequently Colyer Fehr, was a running list of tenders which gave details of each tender, who had been successful in relation to that tender and the price that each bidder had submitted (to the extent that that information could be ascertained). When the bid was won by a domestic purchaser, Colyer Fehr would often describe the successful purchaser as a "local". Whether the local buyer was named or simply described, the list did not indicate whether Colyer Fehr had acted for the local buyer or indeed had bought the tallow in its own name. The list was sent to Kerry on a regular basis.
19A third type of document, also prepared by ARC Holdings and later Colyer Fehr, kept track of the quantities of tallow that KNZA required and showed the extent to which KNZA had tallow to meet those requirements. The last column of the document indicated whether KNZA was short or long in its requirements for each vessel and grade of tallow that Kerry had indicated KNZA required. Documents of this type were produced weekly but it was Mr Evans Snr's practice, which again was followed by his son, to destroy the documents shortly after the end of the week to which they related. Consequently, few of them remain in existence.
20In addition to the documents I have referred to, Colyer Fehr also kept what it called "contract books". These books, which were started by Mr Evans Snr in 1991, recorded all purchase and sale contracts which ARC Holdings or Colyer Fehr entered into, both for themselves and for other parties. Each contract entered into for KNZA was assigned a unique number in the contract book, beginning with the prefix "E", and then later "K", or occasionally no prefix. Non-KNZA contracts were not assigned numbers. On taking over the business, Mr Evans Jnr says that he only recorded contracts in the contract books that had been entered into on behalf of KNZA, although, in fact, some other sales were also recorded in the books from that time. There is a question whether, in those circumstances, the books accurately record the purchase of tallow on behalf of KNZA. In my view, they do. I accept Mr Evans Jnr's evidence that he recorded all contracts entered into on behalf of KNZA. The fact that some other contracts are recorded in the books after Mr Evans Jnr took over the principal role of buying tallow on KNZA's behalf is explained by the fact that Mr Evans Snr continued on occasions to buy tallow and, when he did so, he followed his past practice of recording all sales in the books.
21Generally, Mr Evans Snr and Mr Jones, and later Mr Evans Jnr and Mr Spence, discussed the bids that Colyer Fehr would lodge on behalf of KNZA for each batch of tallow offered for tender. However, in some cases, Colyer Fehr was given a discretion to bid an extra $5 per tonne, and in some cases Colyer Fehr was given a more general discretion to determine the price at which it would bid on KNZA's behalf. In the case of smaller suppliers, Colyer Fehr sometimes lodged a bid on behalf of KNZA without any instructions; and sometimes it lodged a bid in the expectation of failing simply in order to be seen as having a continuing interest in the relevant supplier's product.
22When KNZA was successful in a tender, Colyer Fehr arranged for collection and transport (if sold ex-works) or for the delivery (if sold delivered) to one of KNZA's terminals. It also faxed KNZA a purchase slip which recorded the price, expected grade and likely quantity of the tallow that it had purchased. The tallow that was the subject of a particular tender was normally produced and delivered progressively. Colyer Fehr would arrange for the delivery or collection of each batch and notify Kerry at that time of the precise quantity and quality supplied. It would generally arrange for the producer to invoice KNZA directly for each batch of tallow as it was supplied and would invoice KNZA separately for its commission of $5 per tonne. Colyer Fehr did not normally advise Kerry specifically if there was a variation in the quantity supplied compared to the amount for which KNZA had successfully tendered.
23In addition to advising Kerry in relation to the market, submitting tenders on behalf of KNZA and arranging for the delivery of tallow to KNZA's storage tanks, Colyer Fehr also performed a number of other services for KNZA. On some occasions, KNZA required tallow urgently to fill a particular order that had not been anticipated. On those occasions, Mr Evans Snr or Mr Evans Jnr arranged to fill those requirements by "borrowing" tallow from another tallow purchaser (such as Meadow Lea), or diverting tallow from a production that had been won by someone else on a tender, or by purchasing tallow off-tender by negotiation. Colyer Fehr also, on occasions, negotiated exclusive supply arrangements with particular producers on KNZA's behalf. In addition, Colyer Fehr negotiated container freight rates, tested and monitored tallow supplied by producers and renegotiated prices if the tallow proved to be off-specification, arranged for some tallow to be processed and for some to be placed in drums, arranged for tallow to be loaded or discharged from bulk tanker ships and arranged long term storage and transport contracts. In many cases, these additional services were supplied by Colyer Fehr itself, for which, depending on the nature of the service, it charged an additional fee. For example, in the financial year ending 30 June 2004, KNZA paid Colyer Fehr $469,046 in commission under the agreement, $554,122 for tallow cartage, $78,586 for tallow drumming and $172,577 for the storage, cartage and discharge of vegetable oil. In other years, it also paid Colyer Fehr for bleaching tallow.
24While KNZA purchased tallow in Australia for export, it did not carry on a business of selling tallow domestically. During cross-examination, Mr Spence suggested that KNZA was willing and able to do so, but did not do so as opportunities to sell domestically were not presented to it by Colyer Fehr. I do not accept that evidence. With one exception, there is no evidence that anyone from Kerry or KNZA told Colyer Fehr that it was interested in selling tallow domestically. The exception is that Mr Spence told Mr Evans Snr in about March 2006 that KNZA was considering selling tallow to Gull Petroleum in order for it to manufacture a form of bio-fuel. That aside, Mr Spence could not recall in cross-examination any occasion on which KNZA had sought out a domestic customer or asked Colyer Fehr to do so on KNZA's behalf. I do not think that that one example demonstrates that KNZA had a serious interest in selling tallow domestically. Moreover, it is difficult to see what contribution KNZA could make in the domestic market that would attract local buyers to it. Its activities were clearly directed to the export of tallow.
25ARC Holdings and Colyer Fehr were more successful in acquiring tallow for KNZA than the parties had expected. In the first year (1992), ARC Holdings acquired approximately 95,000 tonnes. That figure increased over subsequent years and reached a peak of approximately 130,000 tonnes in 1999 and then gradually declined to approximately 80,000 tonnes by the time the agreement was terminated. The reason for the decline is not entirely clear from the evidence. Mr Spence puts it down to increased competition from CTG. However, Mr Spence conceded in cross-examination that Colyer Fehr had done a good job in acquiring tallow for KNZA, and he did not suggest that Colyer Fehr had failed to acquire sufficient tallow for KNZA in order to permit it to fulfil its contractual obligations to its customers.
26As I have said, Colyer Fehr took over the role of acquiring tallow for KNZA from ARC Holdings following Mr and Mrs Evans Snr's acquisition of the shares in Colyer Fehr at the beginning of May 1993. Mr Evans Snr says that he met with Mr Spence in Kerry's offices in New Zealand at that time. He was in New Zealand to finalise the purchase of the shares in Colyer Fehr. At the meeting, Mr Evans told Mr Spence that he intended from then on to carry on business in the name of Colyer Fehr. Mr Evans says that at that meeting he made a reference to ARC Holdings having sold 200 tonnes of drummed tallow per month, that that comment had upset Mr Spence and that Mr Evans had responded in words to the effect of:
Relax, Hugh. I was having you on. We haven't been exporting that much tallow.
Mr Evans said that he made the comment he did because he had a large number of drums which he had hoped to sell to Kerry and that he was trying to encourage Kerry to sell more drummed tallow itself. Mr Evans says that Mr Spence is mistaken when he suggests that a conversation concerning drummed tallow occurred at the time it was agreed Mr Evans would buy tallow on behalf of KNZA.
